Since when did it become the norm for UPS to ring your doorbell and take off running when they deliver packages? You should've seen this delivery lady that just delivered a package to my door. She rang the doorbell and I swear she was back in her truck and pulling away before I even had a chance to get out of my chair.
Incidentally, I used to do something similar to this in high school. But I wasn't delivering packages (at least nothing anybody would ever want). And I almost got myself shot. Ah, the glory days.
