jmac, 
I forgot who I heard it from (was it you?) but I like this piece of advice for folks who are aunts/uncles/mentors/whatever to modern younguns:
The kids you know are not interested in treating you like you're one of them. This is because you're not one of them.
Here's what you can be for them, uniquely: a grown-up who they can trust not to be weird about whatever it is they do share with you. Aim for that.
