fuck 'em. Smoke as much as you want. I only have one friend who's ever given me shit for not wanting to smoke with him when I had shit to do. I fuckin smoked his ass out until *he* couldn't hang anymore later on that night and he was like "Damn dude, I thought you were a rookie or something" Shit, I've been smoking for 13+ years and he's thinkin' I'm a rookie!! haha!
