Mine don’t go out in the eves yet, drinking etc - I bet that stage is the most worrying.
Mine haven't been through that stage, and I doubt they will before college. Mainly because we're in the US, and it's both illegal and socially fairly unacceptable.
They start driving at 16, and they like being able to do so. They know that if they went out and got drunk they'd lose that privilege ASAP.
They'd also lose privileges at school like being allowed to be in the school play, sports teams etc - for both of them that would be fairly devastating.
But mainly, it's just not something their friendship groups do, so it's not something they expect to do. It definitely seems to make life easier at the teen stage.
My oldest is at university and I know there's much more access to alcohol there, but I also know she's not driving anywhere, she's always with friends who'll look after her, and she's always on or close to campus.
