door

i feel terrible. i was going downtown today to meet my brother and father for lunch. i parked. got some change out of my car. opened my door. then.....SMACK! a biker. i totally doored this guy and he flew off his bike and landed on his head on the asphalt. he seemed to be shaken up, but ok. i called an ambulance for him and then had to file an accident report with the cops. i just feel really terrible about it.
