My son's coach sent out an email to the team saying that if anyone *found* the lost MP3 player, could they please return it, no questions asked, and someone did! I cannot wait to tell my son he's off the hook for the $50. I even tried to call him at school because I wanted to take that weight off his shoulders (evil HH wanted to make him stew a bit) but I couldn't get through to him.
He's still grounded to make the point he needs to be more careful. I think the lesson has been learned.
