diannescruffy, can i ask was that the one with the 14yr old girl?

If so she said on TV that if she could say one thing to other kids is to just tell your friend to STOP, pull over and just get out and call someone else to come get them (thats for speeding not drinking).

I def think now is the time to have a chat with him though, not a lecture just a sit down and ask how he feels about what his friend went through and what he would do in the same situation.

I think all parents worry but in the long run it's hard as we can't control what they do, we can only make sure they are well informed, know that your there for him and hope he makes the right decisions.
I'm sure you have raised a smart and well aware young man.
