I don't mind changing my mind if Josh has a valid argument, like S did about the toys.
I think Josh is about to face a disappointment. He's writing a little play and he's going to recruit volunteers to be in it at his birthday party. I'm afraid nobody will want to do it, but I think I should let him try, instead of warning him in advance that it might not be something his friends want to do. I'm just afraid he's going to be hurt if they say no. Such is parenting, I guess!
