In my mind, it didn't matter that Darcy and Ethan never kissed, or that it was only the fifth grade, or that they "broke up" two weeks later when Darcy lost interest and decided that she liked Doug Jackson again. Or that, as my mother told me for comfort, imitation is the sincerest form of flattery. It only mattered that Darcy stole Ethan from me. Perhaps she did it because she really did change her mind about him; that's what I told myself so I would stop hating her. But more likely Darcy took Ethan just to show me that she could.

So, ladies and gentlemen of the jury, in a sense, Darcy Rhone had this coming to her. What goes around comes around. Perhaps this is her comeuppance.

I picture the faces of the jury. They are not swayed. The male jurors look bewildered-as if they miss the point altogether. Doesn't the prettiest girl always get the boy? That is precisely the way the world should work. An older woman in a sensible dress purses her lips. She is disgusted by the mere comparison-a fiance to a fifth-grade crush! Good heavens! A perfectly groomed, almost beautiful woman, wearing a canary-yellow Chanel suit, has already identified and allied herself with Darcy. There is nothing I can say to change her mind or mitigate my offense.

The only juror who seems moved by the Ethan tale is a slightly overweight girl with a severe bob the color of day-old coffee. She slouches in the corner of the jury box, occasionally shoving her glasses up on her beak of a nose. I have tapped into this girl's empathy, her sense of justice. She is secretly satisfied by what I did. Maybe because she, too, has a friend like Darcy, a friend who always gets everything she wants.

I think back to high school, when Darcy continued to get any boy she wanted. I can see her kissing Blaine Conner by our locker and recall the envy that would well up inside me when I, boyfriendless, was forced to witness their shameless PDA. Blaine transferred to our school from Columbus, Ohio, in the fall of our junior year, and became an instant hit everywhere but in the classroom. Although he wasn't bright, he was the star receiver on our football team, the starting point guard for our basketball team, and, of course, our starting pitcher in the spring. And with his Ken-doll good looks, the girls loved him. Doug Jackson, part two. But alas, he had a girlfriend named Cassandra back in Columbus to whom he claimed to be "110 percent committed" (a jock expression that has always bugged me for its obvious mathematical impossibility). Or so he was before Darcy got in the mix, after we watched Blaine pitch a no-hitter against Central and she decided that she had to have him. The next day she asked him to go see Les Miserables. You'd think a three-sport jock like Blaine wouldn't be into musicals, but he enthusiastically agreed to escort her. After the show, in Darcy's living room, Blaine planted a large hickey on her neck. And the following morning, one Cassandra of Columbus, Ohio, was dumped on her ear.

I remember talking to Annalise about Darcy's charmed life. We often discussed Darcy, which made me wonder how much they gossiped about me. Annalise contended that it wasn't only Darcy's good looks or perfect body; it was also her confidence, her charm. I don't know about the charm, but looking back I agree with Annalise about the confidence. It was as if Darcy had the perspective of a thirty-year-old while in high school. The understanding that none of it really mattered, that you only go around once, that you might as well go for it. She was never intimidated, never insecure. She embodied what everyone says when they look back on high school: "If I only knew back then."

But one thing I have to say about Darcy and dating is this: she never blew us off for a guy. She always put her friends first-which is an amazing thing for a high school girl to do. Sometimes she blew her boyfriend off altogether, but more often she just included us. Four of us in a row at the theater. The flavor of the month, then Darcy, then Annalise and me. And Darcy always directed her whispered comments our way. She was brash and independent, unlike most high school girls who allow their feelings for a boy to swallow them up. At the time, I thought she just didn't love them enough. But maybe Darcy just wanted to keep control, and by being the one who loved the least, that is what she had. Whether she did care less or just pretended to, she kept every one of them on the hook even after she cut them loose. Take Blaine, for example. He is living in Iowa with a wife, three kids, and a couple of chocolate Labs, and he still e-mails Darcy on her birthday every year. Now that is some kind of power.

To this day Darcy talks wistfully of how great high school was. I cringe whenever she says it. Sure, I have some fond memories of those days, and enjoyed moderate popularity-a nice fringe benefit of being Darcy's best friend. I loved going to football games with Annalise, painting our faces orange and blue, wrapping up in blankets in the bleachers, and waving to Darcy as she cheered down on the field. I loved our Saturday-night trips to Colonial Ice Cream, where we always ordered the same thing-one turtle sundae, one Snickers pie, one double-chocolate brownie-and then split them among us. And I loved my first boyfriend, Brandon Beamer, who asked me out during our senior year. Brandon was a rule-follower too, a Catholic version of me. He didn't drink or do drugs, and he felt guilty even discussing sex. Darcy, who lost her virginity our sophomore year to an exchange student from Spain named Carlos, was always instructing me to corrupt Brandon. "Grab his penis like this, and I guarantee, it's a done deal." But I was perfectly happy with our long make-out sessions in Brandon's family station wagon, and I never had to worry about safe sex or drunk driving. So if my memories weren't glamorous, at least I had a few good times.

But I also had plenty of bad times: the awful hair days, the pimples, the class pictures from hell, never having the right clothes, being dateless for dances, baby fat that I could never shed, getting cut from teams, losing the election for class treasurer. And the overwhelming feeling of sadness and angst that would come and go willy-nilly (or, more accurately, once a month), seemingly out of my control. Typical teenager stuff, really. Cliches, because it happens to everyone. Everyone but Darcy, that is, who floated through those tumultuous four years unscathed by rejection, untouched by the adolescent ugly stick. Of course she loved high school-high school loved her.

Many girls with this view of their teenage years seem to really take it on the chin later in life. They show up at their ten-year reunion twenty pounds heavier, divorced, and reminiscing about their long-gone glory days. But the tide of glory days hasn't ebbed for Darcy. No crashing and no burning. In fact, life just keeps getting sweeter for her. As my mother once said, uncharacteristically, Darcy has the world by the balls. It was-and still is-the perfect description. Darcy always gets what she wants. And that includes Dex, the dream fiance.

I leave Darcy a message on her cell, which will be turned off during the movie. I say that I am too tired to make it to dinner. Just getting out of going makes me less queasy. In fact, I am suddenly very hungry. I find my menus and call to order a hamburger with cheddar and fries. Guess I won't be losing five pounds before Memorial Day. As I wait for my delivery, I picture Darcy and me playing with the phone book all those years ago, wondering about the future and what age thirty would bring.

And here I am, without the dashing husband, the responsible babysitter, the two kids. Instead my benchmark birthday is forever tainted by scandal… Oh, well. No point beating myself up over it. I hit redial on my phone and add a large chocolate milk shake to my order. I see my girl in the corner of the jury box wink at me. She thinks the milk shake is an excellent idea. After all, doesn't everyone deserve a few weak moments on her birthday?

Chapter 3

When I wake up the next morning, the cavalier girl sucking down a milk shake is gone, caved to guilt and thirty years of rule-following. I can no longer rationalize what I did. I committed an unspeakable act against a friend, violated a central tenet of sisterhood. There is no justification.

So on to Plan B: I will pretend that nothing happened. My transgression was so great that I have no choice but simply to will the whole thing to go away. And by proceeding with business as usual, embracing my Monday-morning routine, this is what I seek to accomplish.

I shower, dry my hair, put on my most comfortable black suit and low heels, take the subway to Grand Central, get my coffee at Starbucks, pick up The New York Times at my newsstand, and ride two escalators and one elevator up to my office in the MetLife Building. Each part of my routine represents one step further from Dex and the Incident.

I arrive at my office at eight-twenty, way early by law-firm standards. The halls are quiet. Not even the secretaries are in yet. I am turning to the

Metro section of the paper, sipping my coffee, when I notice the blinking red message light on my phone-usually a warning that more work awaits me. Some jackass partner must have called me on the one weekend in recent memory when I failed to check my messages. My money is on Les, the dominant man in my life and the biggest jackass partner amid six floors of them. I enter my password, wait…

"You have one new message from an outside caller. Received today at seven-forty-two A.M…" the recording tells me. I hate that automated woman. She consistently bears bad news and does so in a chipper voice. They should adjust that recording at law firms, make the voice more somber: "Uh-oh"-with ominous Jaws music in the background-"you have four new messages…"
