I'm fine; my car's probably not damaged enough to be worth repairing. But I have learned a life-lesson today. Albeit one with limited applicability. But maybe if I share it, it will do somebody some good.
When some asshole rams your car and takes off — and you manage to read his license plate and keep repeating it to yourself as you call 911, do not stop repeating it when the 911 operator answers, in order to listen to and answer their questions. Instead, keep repeating it, clearly, until you are quite certain that it has been recorded. Then answer the 911 operator's questions. Otherwise, it just may turn out that by the time you've answered their questions, you no longer recall the damned license plate number. Thereby letting the asshole get away with it.
