I'm going to clarify a little bit for you so you can understand what happened. Karen was driving and a dog ran out in front of her car and she hit it. Of course, she jumped out to try and help the dog and it proceeded to bite her. Obviously, it was frightened and probably hurting. I know Karen will explain more to you all, later, but perhaps this helps a little bit. It is definitely the "condensed" version! :p
I hope you enjoy the movie and your dinner, Karen. Take that deep breath that we talked about and try to relax
Love,
Logan
