My mailman once dropped a GameFly envelope on the ground when he put my mail in the mailbox, which was on the side of a road. Luckily I was home at the time and saw the mail truck pass by and went to my mailbox immediately.
When I was walking towards the mailbox, I noticed a bright colored piece of paper on the ground. When I got closer, it turns out it was a GameFly envelope. I couldn't believe it.
