No one saw it

You just got out of the movie theater with a few friends. You say good-bye to your buddies and walk to your car. Your car is parked at the end of the parking lot because you arrived to movies late. You jump into the car and pop it in reverse. You press on the gas too hard and bash into another car. You get out to look at the damage. Its just a fender bender, but you can tell that the car hit. You look to see if anyone is around. No one is in sight and you are in the far dark corner of the parking lot. Do you wait, leave a message with your information, or do you go home?
