But the fact that everyone I know from AEHS is here, including both Moscovitz siblings—that’s exciting. I wasn’t expecting that.

And I know it’s wrong to be excited to see my ex-boyfriend when I’m out on a date with my current boyfriend.

However, that is not my fault. It’s MHC.

Our seats are rows and rows apart so there’s no chance of my being overpowered by eau de Michael. Unless somehow we bump into him later. Which I highly doubt is going to happen.

Anyway, Michael’s alone. He didn’t come with a date! Which may be because Micromini Midori is in Genovia.

Except that I can’t help wondering if he came solo because I said in my e-mail to him that I’d be coming.

But then I remembered what Boris said—about how the two of them are going to be living together this year. So I guess that’s why he’s here, actually. To support his friend.

Stupid me, getting my hopes up. AGAIN.

Anyway. I guess I should be getting back to my seat. I didn’t want to be rude and write while I was supposed to be looking like I was paying attention, but—

WAIT.

Oh, God.

I recognize those shoes.

Thursday, May 4, 8:30 p.m., ladies’ room, Carnegie Hall

I was right: They were her shoes.

I totally confronted her when she came out of her stall.

Well, confronted isn’t the right word. I asked her about the commercial she made for my dad. Why she did it, I mean.

At first she tried to get out of it by saying it had been a birthday gift for me.

And it’s true, she had said, back in the Atom office when I turned in my story about Michael, that there was something she’d been going to give me for my birthday. And she’d said to give it to me, she’d need to come to my party. She just hadn’t said she was going to give it to me at my party. I’d assumed that part.

But…why now? Why a present this year? And such a great present?

At first she looked really annoyed that I wouldn’t just let it go. Like she couldn’t believe she’d walked into the bathroom and there I was.

I guess it probably does seem like every single time she goes for a pee, there I am.

Well, it’s basically true. It’s like I have some kind of Lilly Moscovitz bladder radar.

And this time Kenneth wasn’t around to ask weird questions about whether or not I was still going out with J.P., and keep her from answering. For a second I thought she wouldn’t anyway.

But then she seemed to make a decision within herself. She sort of sighed and, looking a bit annoyed, went, “Fine. If you must know, Mia…my brother said I had to be nice to you.”

I just stared at her. It took a few seconds for her words to register. “Your brother said?…”

“That I had to be nice to you,” Lilly finished for me, sounding exasperated, as if I should have been aware of this. “He found out about the website, okay?”

I moved from staring to blinking. I was making progress. “Ihatemiathermopolis.com?”

“Right,” Lilly said. She did look a little ashamed of herself, actually. “He was really mad. I’ll admit…it was pretty childish.”

Michael found out about ihatemiathermopolis.com? You mean…he hadn’t known? I thought everyone in the whole world had known about that stupid website.

And he’d told Lilly she had to be nice to me?

“But.” I was having trouble processing so much information at once. It was like I was a desert that was finally getting rain…only there was too much of it, and I couldn’t soak it all in. Soon I’d be experiencing mud slides. And flash floods. “But…why were you so mad at me in the first place? I’ll admit, I acted like a total jerk to your brother. But I regretted it, and I tried to get back together with him. He’s the one who said no. So why were you so mad about it?” This was the part I could never figure out. “Was it…was it just because of J.P.?”

Lilly’s face darkened. “You don’t know?” she asked, sounding incredulous. “You honestly don’t know?”

I was definitely experiencing sensory overload. “No.” I shook my head. She hadn’t actually answered the question. “What am I supposed to know?”

“I have never,” Lilly said flatly, “met anyone so dense as you in my life, Mia.”

“What?” I still have no idea what she was talking about. I know I’m dense. I do! I’m a geek. She didn’t have to rub it in. She could have helped me a little. “Dense about what?”

But at that point an old lady came into the bathroom, and I guess Lilly decided she’d said enough. She just shook her head, and walked out.

Which just leaves me here to wonder, as I have a million times before: What is it I’m supposed to know? What is it that Lilly thinks I’m so dense about?

It’s true I started dating J.P. right after the two of them broke up. But she was already not speaking to me by the time that happened. So that can’t be it.

Why can’t Lilly just tell me what it was I was so dense about? She’s the genius, not me. I hate it when geniuses expect the rest of us to be as smart as they are. It’s not fair. I’m of average intelligence, and I always have been. I’m creative, and stuff, but I’m romance-novel-writing creative! I don’t perform well on IQ tests, and certainly not SATs (obviously).

And I’ve NEVER been able to figure out Lilly.

And I can’t figure out her brother, either. For instance, why does Michael care whether she starts being nice to me or not?
