My nephew's lived with me for a couple months now, my sister was pretty messed up and wound up in jail. I've always been kind of like a dad/big brother to him (I'm 26) and think I'm actually a pretty good influence overall, I've taught him to work on cars, hunting and fishing, help him with girls, the kind of stuff he needs without a dad or big brother around. But I'm kind of a regular working class guy, I use a lot of profanity, smoke a pack a day, drink and on and on. I feel like I shouldn't just let my nephew hang out with me and smoke too but he's been smoking since he was 14 so it'd be kind of out of the blue to just tell him to quit. I don't know, what do you think?
