Whyyyyyy

So there's a guy who's friends with one of my friends. He's a junior, and I'm a Freshmen. He's sooo cute, and funny and seems awesome. And he wants to get with me (we just met the other day). But he's an alcoholic, and a stoner, and he's probably only interested for sex. Just my luck. First person who's into me in FOREVER is someone that I can't/wouldn't date.
