Just after Seb got ill, Anna spent a night at her boyfriend's house, and she's been acting differently ever since.
She still talks to me and everything, but I get the impression she doesn't really care what I say.
One day, I sit next to her and she just looks at me.
"Hi," I say pointedly.
She rolls her eyes. "Hi."
"Are you all right?" I test, knowing I'm annoying her.
"I'm fine, Lola. Why wouldn't I be?"
"No reason. You look a bit tired, that's all."
She sighs. "Well, I caught my boyfriend doing weed again and my mum won't let me go to his house any more."
"Can't imagine why that is," I say quietly.
She hears anyway. "I know, right? Anyway, has Seb still got selective mutism?"
"Seb has never had selective mutism."
"Whatever. Is he still anorexic?"
"He's never been anorexic."
Anna blinks at me. "Bulimic, then. God, Lola, it's the same thing."
"No it isn't," I say. "And he's never been bulimic either."
"Whatever," she says again. "Have you got a lighter."
I look at her in absolute shock. "Excuse me?"
She looks back as if she's just realised something. "Right, I forgot. You don't smoke. Sorry."
I almost choke. "What the hell? Why would I? Since when do you?"
She rolls her eyes. It's a habit she had before, but I didn't really mind it then. Now, it's really irritating.
"God, Lola. It's not a big deal. It's not like I'm smoking weed like-"
"No, it's worse!" I exclaim, getting up. "D'you know more people die from cancers caused by smoking than they do from anything caused by cannabis?"
"Yeah," she says. "Right. Sure they do. You're acting like you're my mother or something."
I can't take it any more. If I don't tell her what I'm thinking, I might explode.
"You know, Anna, you've turned into a complete cow. And it's every since you slept at your boyfriend's house. I'm not stupid. t's because you had sex with him, and now you're trying to impress him by becoming a complete and utter moron."
"Oh. My. God. Lola. What do you think I am? I haven't had sex with him! I mean, yeah. We, like, did some stuff, but we didn't have sex. God."
I am ever so slightly relieved. For a moment, I thought her brain had melted. "Good. You shouldn't. You're not old enough, and you've only bee going out four months."
Again, she rolls her eyes. "You know what? I've changed my mind. He wants it, and I'm going to give it to him."
"Then you," I tell her, "Are an absolute idiot."
And I walk off.
