Inverse:
The inverse of a conditional statement is formed by denying both its hypothesis and conclusion.
So:
Logically equivalent:
A conditional statement: a b
The contrapositive of the statement: not b not a
Logically equivalent:
The converse of the statement: b a
The inverse of the statement: not a not b
I’m sorry. WHAT?
Okay, once again, I have managed to prove to be the exception to the rule. If people who are bad at Algebra are supposed to be good at Geometry, then I should be the Stephen Freaking Hawking of Geometry, but guess what? I don’t understand a WORD of this.
Plus, Mr. Harding? Yeah, could he BE any meaner? He already made Trisha Hayes cry over her isosceles triangles, and that’s virtually impossible, since she’s one of Lana Weinberger’s cronies, and also I’m pretty sure she’s a female cyborg like in Terminator 3.
He’s being totally nice to me, but that’s just because one of his colleagues is my stepdad. Oh, and the princess thing, of course. Sometimes it actually doesn’t hurt to have a six-foot-five-inch Swedish bodyguard sitting behind you.

Oh, well. At least I have ONE good teacher. Ms. Martinez is SO cool. It’s so nice to have a teacher who is still close enough to our age to know about stuff like rubber spike bracelets and The OC.
As Ms. Martinez was collecting our writing samples on how we spent our summers, she was like, “And I just want you guys to know that you can come to me with questions about anything, not just English. I really want to get to know all of you as PEOPLE, not just as my students. So if there’s anything—anything at all—you want to talk about, feel free to stop by. There is an open-door policy in my classroom, and I will always be here for you.”
Whoa! A teacher at Albert Einstein High who doesn’t disappear into the teachers’ lounge the minute class is over? Unbelievable!
Except I sort of wonder how long Ms. Martinez is going to hang on to her open-door policy, because as I was leaving I noticed, like, ten people scurrying up to her desk to talk to her about their personal problems. Lilly was totally the first one in line.
I hope Ms. Martinez counsels Lilly just to let the whole Boris thing go. I didn’t want to say anything to Tina, but her boyfriend’s summer transformation into a hottie is fully why Lilly is wigging out today, not PMS like I told Tina. It must totally suck to see the guy you dumped transformed into Orlando Bloom before your very eyes.
If Orlando Bloom had no fashion sense and breathed from his mouth, I mean.
I hope Lilly doesn’t wear Ms. Martinez out so much that she doesn’t have time to read our writing samples tonight. Because I’m sure that when she’s done with mine, she’s going to want to submit it to a literary agent or something and get me a book deal. I realize fifteen is pretty young to have a multi-book deal with a major publishing house, but I’ve handled the princess thing pretty well so far. I’m sure I could handle a couple of book deadlines.

Boy. He’s wearing pants!
Hello. So am I. I forgot to shave my legs this morning.
Oh. OH.
Yeah. See what I mean?
Well, what’s his/her name?
Perin. At least that’s what Mademoiselle Klein said when she called roll.
Is Perin a boy’s name or girl’s name?
I don’t know. That’s why I’m asking you.
Wait, I wasn’t paying attention during roll. Did
Mademoiselle Klein say Per-ran or Per-reen? Because if she’s a girl, it would be Per-reen in French, right?
Yeah, but Mademoiselle Klein doesn’t call roll in French. She just said Perin in English with no accent.
So in other words…this is a mystery.
Totally. I just want to know whether or not to think he’s cute.
Okay. Here’s what we’ll do. We’ll keep an eye on him/her, and see which bathroom he/she goes into before lunch. Because everyone goes to the bathroom before lunch to put on lip gloss.
But not boys.
Exactly. If he doesn’t go to the bathroom, he’s a boy, and then you can like him.
But what if he’s a girl who just doesn’t wear lip gloss?
Argh! Mysteries are okay in books, but in real life, they kind of suck.

WHY? WHY WHY WHY did I think this year was going to be better—in spite of Michael not being around—than last year, just because at least Lana and Josh wouldn’t be making out in front of my locker?
Because the thing is, when Josh was around, Lana was DISTRACTED, and not actively seeking out targets to destroy.
But now that there’s no man in her life, she has ample free time to torture me again. Like today at lunch, for instance.
It was all my fault in the first place for being greedy and going back to the jet line for a second ice-cream sandwich. Really, one ice-cream sandwich ought to be enough for a girl my size.
But there was something wrong with the three-bean salad. You would think that with all the money the trustees invested in those surveillance cameras outside they’d have tossed just a LITTLE the cafeteria’s way so we could get something decent to eat in here besides frozen dairy products. But no. Lilly seems to have a point: Apparently finding out who is stubbing their cigarettes out on Joe’s head is more important than providing digestible sustenance for the student body.
