I did not force or demand or even encourage her after the first conversation. I said I thought it would be OK but it is up to her. And (Baba forgive me) I gave her a credit card to pay for what S15 needs.

I also suggested that she ask whether he prefers to come along or she could drop him off at the commuity center and he could play basketball while Mrs. Hold and S15 shop. So I agree with your idea of dropping him off.

I am not enthusiastic about leaving someone else's 15 year old son alone with D13. Or alone in our house assuming we find somwhere else for her to go. He is basically a good kid but stuff happens.

When you can see it coming, duck!
