What would you do?
If you were this other parent, what would you want me to do?
Bonus - apply this to adults, too. What do you do if someone wants to get together some time, and that's not how you want to spend your time? Have you ever emailed a friend an open-ended invitation like that, and they didnt reply? What did you make of that?
(Latest installment: my kid says, well, okay, I guess, invite her over. Does that change your answers?)
