Bless you for doing all the right things - stoppping, calling the police, helping with Missy, and trying to calm that poor man who hit her. That part made me cry because two years ago some ass**** hit (& KILLED) my sweet Rosie. When I ran out, only 1 other man had stopped to help. It was pitch black & pouring rain. The ass**** that hit her drove back 10 minutes later to ask who was going to pay for his truck fender. Never said "how is she?" or "I'm sorry", or not even "Gee, I didn't see her".
I'm glad to hear that Missy will be alright
