I honestly don't know how I feel about this. I'm yet to be a parent of a teenager but that clock is ticking.
My initial thought is, by the time my kids are able to get into situations which are "getting weird", I hope they're equipped to extricate themselves without needing this kind of cover call from dad. I mean, what if I didn't check my messages or something?
I really hope my kids are confident enough to say that they don't feel comfortable with something and just leave.
