I hope the little squirrel was ok, but don't worry about it. It was a total accident. Animals dart in front of people all the time and sometimes it happens so fast that you don't have time to stop. I was driving on the highway one day not long ago and a little skunk ran right in front of me. I almost hit it but luckily I was able to clow down and it scurried across into the ditch somewhere, but unfortunately I wasn't as lucky about a month ago when I was driving home in the dark. A little rabbit ran right infront of me. I couldn't have been going any faster than 15-20 mph. but it ran right in front of me and I didn't have time to even put on the brakes. I felt so bad and cried afterward, but it was just an accident and I couldn't help it. It was the first animal I had ever hit and I hope it's the last.
