i agree with illusional...i think it's easy to begin a conversation with someone if she's in the same class as you or if you'd seen them before. i remember i had a crush on a guy who'd i'd always see in my history class. i was too scared to talk to him in history and the semester went by without me talking to him, but luckily he ended up in my theater class. so i started talking to him about the history class from last semester and mentioned i'd seen him before. hope this helps a little....
I'd rather be an optimist who's wrong instead of a pessimist who's right
