I know he meant well and was just trying to be a matey Dad (BF seems nice but is not very forthcoming, think he was just trying to break the ice a bit) but I think I'd be quite pissed off if someone one gave DD (14) alcohol without me knowing - we allow her some at home but that's our decision under our roof.
I like a drink and drank from around the same age so am not being a prude but I'm just not sure it's our decision to make.
