I'm a fairly relaxed parent (I hope) without going overboard on the "not caring", my DS2 spends quite a lot of time "hanging around" with his friends. We live in a small town, where there are loads of teenagers harmlessly "hanging around" in the parks and sports grounds, there is very little trouble (in 12 years I've never heard of any violence), no gangs etc, although there is certainly an element that is into drinking, drugs etc. My logic has always been that a) we are well known to everyone and I would hear about it if he was doing anything he shouldn't and b) that I would trust him unless he proved that I was wrong to do so. I know that 1 of his friends but until yesterday I would have sworn that DS wouldn't do so. Last night I was told by a friend that he was seen getting into a car and smoking. I wasn't aware that any of his friends was old enough to drive. He still swears that he doesn't smoke, that his friends do and he sits in the car while they do so. (Obviously there are dangers about passive smoking). AIBU to ground him for a while, at the same time as having a long chat about the company he keeps and passive smoking?
