First 'date' advice?

>< Yeah. Kinda lame asking through here, but yeah. So tomorrow after school, this girl and I are gonna go hang out. We both confessed that we liked each other. We've known each other for like 2 weeks now. Mostly talked through instant messanger. I sit behind her in cl. I'm probably gonna be all self concious, my hair and like my clothes. I postponed it to Monday(tmr) from Friday (last week) because I have had a pimple on my nose for the longest time. And I hoped it would get better, but it hasn't really. I've been using Proactive for like 1 and a half weeks. Damn. Anyways, we're just going to the library to 'get to know each other better'. That means we'll be talking a lot. Uhmm what's good to talk about? I don't want there to be like awkward silences, which I know will happen. And I just realized how ugly my hair is and how skinny I am. And I feel like I've been putting on weight. My gut's like.. almost protruding. Blah. Any advice on any of these subjects would be helpful. Thanks.
