They did n't want to call the police .They did n't want to be held responsible for the animal .None of the above choices .They did n't notice that they hit an animal .
What may be the reason that the car kept driving ?
The person who hit it did n't stop or turn around . I pulled over and walked back to the side of the road . I saw a hunk of bone missing from its leg , and then I looked towards the grass and there it was , popped out .
