Not sure if my judgement here is clouded as I don't go out of an evening socialising with friends. If I meet a friend it's usually in the day when we are child free, rarely in the evening. Dh goes out with a friend every Sunday night, gets in around midnight. His friend smokes like a trooper and dh usually comes in smelling of smoke and alcohol, which I hate. He has suggested staying overnight with the friend and he'll have a shower and come home when the kids wake up. I think doing that every week is too much and I would rather they met up less often. Who is BU?
