There's this girl I go to college with who shall remain unnamed. Every time I go for a smoke after a stressful lecture she's there tagging along - now normally I'd be a little pissed because she never smokes me back and I prefer to smoke alone anyway. Anyway, yesterday I had four hours of exams so I grabbed a glassy from my backpack and headed off to the football fields to have a few bowls and she decided to tag along again. I can't really stand saying no straight up, but seriously, after her being completely off her face after half a bowl and drinking my bottle of Coke I'm not sure what to do about the situation. I hate being straight-up rude to people, and she doesn't seem to get the message that I don't like smoking her up. I'm a chick so I know she doesn't want the D either.. Any advice for my pest control issue ladies and gents?
