Yeah, well, it gets significantly more COMPLICATED when they are young and entering... the
dating years. Especially if, as so many PG kids do, they learn to 'pass' as older more or less invisibly. That's both a good thing and a bad one-- if they DO mention their age, they can come off as insufferably boorish braggarts, and if they don't, then they risk others not realizing JUST how young they actually are-- and there are legal consequences, potentially, for older companions. Some of those potential consequences are quite severe. This is a significant social burden for very young college students, actually.
Another one today-- when your kid does something that is
so material for the ultimate brag thread, but you can't actually, you know,
brag about it... because... it's too identifying.
So I have to be vague. But I can't talk about it with anyone else IRL without sounding insufferable.
