An accident

My first car accident, and it wasn't my fault.

I was calmly sitting at a gas station with my blinker signaling I was turning right while waiting for the traffic to clear sufficiently to let me in. I am a very unoffensive driver.

Suddenly, just as I was moving out, a large bump in the back of the car startled me.
My dad and I had no idea what it was, but he said "Keep going."
So I kept pulling out and as I did so, we both looked behind us. A young man with a purple car had backed out of a parking space and obviously did not look where he was backing into.

So now we have a nice scrape and a crack in my dad's rear bumper, but as Dad says, "That's what bumpers are for."
