I almost hit a kid in the parking lot at the park yesterday
What happened? How did you almost hit him?
He was bumming around behind my car and I didn't see him until I started to back up.
It would have been awful had you hit him. You should be more careful in parking lots in the future.
But he shouldn't have been behind my car.
Even so, it's your responsibility as the driver to pay attention to who is around you and be careful. If you had hit him he might have been seriously hurt.
