I can understand how you feel. That would make me extremely angry too. If I were in the same situation I would put up a little sign asking for it to be returned. Someone should know something. Or if I was really desperate I would call the news and let them know that someone stole it. Someone is bound to return it. Many other petlovers would feel for you. That's me though. Kids can be mean, but then again, they do not understand things the way adults do. The parents should have been paying attention to their kids.
