Darcy is now leaning over the bar, flirting with the twenty-something, aspiring actor/bartender whom she has already told me she would "totally do" if she were single. As if Darcy would ever be single. She said once in high school, "I don't break up, I trade up." She kept her word on that, and she always did the dumping. Throughout our teenage years, college, and every day of our twenties, she has been attached to someone. Often she has more than one guy hanging around, hoping.

It occurs to me that I could hook up with the bartender. I am totally unencumbered-haven't even been on a date in nearly two months. But it doesn't seem like something one should do at age thirty. One-night stands are for girls in their twenties. Not that I would know. I have followed an orderly, Goody Two-shoes path with no deviations. I got straight As in high school, went to college, graduated magna cum laude, took the LSAT, went straight to law school and to a big law firm after that. No backpacking in Europe, no crazy stories, no unhealthy, lustful relationships. No secrets. No intrigue. And now it seems too late for any of that. Because that stuff would just further delay my goal of finding a husband, settling down, having children and a happy home with grass and a garage and a toaster that toasts four slices at once.

So I feel unsettled about my future and somewhat regretful about my past. I tell myself that there will be time to ponder tomorrow. Right now I will have fun. It is the sort of thing that a disciplined person can simply decide. And I am exceedingly disciplined-the kind of child who did her homework on Friday afternoons right after school, the kind of woman (as of tomorrow, I am no longer any part girl) who flosses every night and makes her bed every morning.

Darcy returns with the shots but Dex refuses his, so Darcy insists that I do two. Before I know it, the night starts to take on that blurry quality, when you cross over from being buzzed to drunk, losing track of time and the precise order of things. Apparently Darcy has reached that point even sooner because she is now dancing on the bar. Spinning and gyrating in a little red halter dress and three-inch heels.

"Stealing the show at your party," Hillary, my closest friend from work, says to me under her breath. "She's shameless."

I laugh. "Yeah. Par for the course."

Darcy lets out a yelp, claps her hands over her head, and beckons me with a come-hither expression that would appeal to any man who has ever fancied girl-on-girl action. "Rachel! Rachel! C'mere!"

Of course she knows that I will not join her. I have never danced on a bar. I wouldn't know what to do up there besides fall. I shake my head and smile, a polite refusal. We all wait for her next move, which is to swivel her hips in perfect time to the music, bend over slowly, and then whip her body upright again, her long hair spilling every which way. The limber maneuver reminds me of her perfect imitation of Tawny Kitaen in the Whitesnake video "Here I Go Again," how she used to roll around doing splits on the hood of her father's BMW, to the delight of the pubescent neighborhood boys. I glance at Dex, who in these moments can never quite decide whether to be amused or annoyed. To say that the man has patience is an understatement. Dex and I have this in common.

"Happy birthday, Rachel!" Darcy yells. "Let's all raise a glass to Rachel!"

Which everyone does. Without taking their eyes off her.

A minute later, Dex whisks her down from the bar, slings her over his shoulder, and deposits her on the floor next to me in one fluid motion. Clearly he has done this before. "All right," he announces. "I'm taking our little party-planner home."

Darcy plucks her drink off the bar and stamps her foot. "You're not the boss of me, Dex! Is he, Rachel?" As she asserts her independence, she stumbles and sloshes her martini all over Dex's shoe.

Dex grimaces. "You're wasted, Darce. This isn't fun for anyone but you."

"Okay. Okay. I'll go… I'm feeling kind of sick anyway," she says, looking queasy.

"Are you going to be okay?"

"I'll be fine. Don't you worry," she says, now playing the role of brave little sick girl.

I thank her for my party, tell her that it was a total surprise-which is a lie, because I knew Darcy would capitalize on my thirtieth to buy a new outfit, throw a big bash, and invite as many of her friends as my own. Still, it was nice of her to have the party, and I am glad that she did. She is the kind of friend who always makes things feel special. She hugs me hard and says she'd do anything for me, and what would she do without me, her maid of honor, the sister she never had. She is gushing, as she always does when she drinks too much.

Dex cuts her off. "Happy birthday, Rachel. We'll talk to you tomorrow." He gives me a kiss on the cheek.

"Thanks, Dex," I say. "Good night."

I watch him usher her outside, holding her elbow after she nearly trips on the curb. Oh, to have such a caretaker. To be able to drink with reckless abandon and know that there will be someone to get you home safely.

Sometime later Dex reappears in the bar. "Darcy lost her purse. She thinks she left it here. It's small, silver," he says. "Have you seen it?"

"She lost her new Chanel bag?" I shake my head and laugh because it is just like Darcy to lose things. Usually I keep track of them for her, but I went off duty on my birthday. Still, I help Dex search for the purse, finally spotting it under a bar stool.

As he turns to leave, Dex's friend Marcus, one of his groomsmen, convinces him to stay. "C'mon, man. Hang out for a minute."

So Dex calls Darcy at home and she slurs her consent, tells him to have fun without her. Although she is probably thinking that such a thing is not possible.

Gradually my friends peel away, saying their final happy birthdays. Dex and I outlast everyone, even Marcus. We sit at the bar making conversation with the actor/bartender who has an "Amy" tattoo and zero interest in an aging lawyer. It is after two when we decide that it's time to go. The night feels more like midsummer than spring, and the warm air infuses me with sudden hope: This will be the summer I meet my guy.

Dex hails me a cab, but as it pulls over he says, "How about one more bar? One more drink?"

"Fine," I say. "Why not?"

We both get in and he tells the cabbie to just drive, that he has to think about where next. We end up in Alphabet City at a bar on Seventh and Avenue B, aptly named 7B.

It is not an upbeat scene-7B is dingy and smoke-filled. I like it anyway-it's not sleek and it's not a dive striving to be cool because it's not sleek.

Dex points to a booth. "Have a seat. I'll be right with you." Then he turns around. "What can I get you?"

I tell him whatever he's having, and sit and wait for him in the booth. I watch him say something to a girl at the bar wearing army-green cargo pants and a tank top that says "Fallen Angel." She smiles and shakes her head. "Omaha" is playing in the background. It is one of those songs that seems melancholy and cheerful at the same time.

A moment later Dex slides in across from me, pushing a beer my way. "Newcastle," he says. Then he smiles, crinkly lines appearing around his eyes. "You like?"

I nod and smile.

From the corner of my eye, I see Fallen Angel turn on her bar stool and survey Dex, absorbing his chiseled features, wavy hair, full lips. Darcy complained once that Dex garners more stares and double takes than she does. Yet, unlike his female counterpart, Dex seems not to notice the attention. Fallen Angel now casts her eyes my way, likely wondering what Dex is doing with someone so average. I hope that she thinks we're a couple. Tonight nobody has to know that I am only a member of the wedding party.

Dex and I talk about our jobs and our Hamptons share that begins in another week and a lot of things. But Darcy does not come up and neither does their September wedding.

After we finish our beers we move over to the jukebox, fill it with dollar bills, searching for good songs. I push the code for "Thunder Road" twice because it is my favorite song. I tell him this.

"Yeah. Springsteen's at the top of my list, too. Ever seen him in concert?"

"Yeah," I say. "Twice. Born in the U.S.A. and Tunnel of Love. "

I almost tell him that I went with Darcy in high school, dragged her along even though she much preferred groups like Poison and Bon Jovi. But I don't bring this up. Because then he will remember to go home to her and I don't want to be alone in my dwindling moments of twenty-somethingness. Obviously I'd rather be with a boyfriend, but Dex is better than nothing.

It is last call at 7B. We get a couple more beers and return to our booth. Sometime later we are in a cab again, going north on First Avenue. "Two stops," Dex tells our cabbie, because we live on opposite sides of Central Park. Dex is holding Darcy's Chanel purse, which looks small and out of place in his large hands. I glance at the silver dial of his Rolex, a gift from Darcy. It is just shy of four o'clock.

We sit silently for a stretch of ten or fifteen blocks, both of us looking out of our respective side windows, until the cab hits a pothole and I find myself lurched into the middle of the backseat, my leg grazing his. Then suddenly, out of nowhere, Dex is kissing me. Or maybe I kiss him. Somehow we are kissing. My mind goes blank as I listen to the soft sound of our lips meeting again and again. At some point, Dex taps on the Plexiglas partition and tells the driver, between kisses, that it will just be one stop after all.

We arrive on the corner of Seventy-third and Third, near my apartment. Dex hands the driver a twenty and does not wait for change. We spill out of the taxi, kissing more on the sidewalk and then in front of Jose, my doorman. We kiss the whole way up in the elevator. I am pressed against the elevator wall, my hands on the back of his head. I am surprised by how soft his hair is.
