I saw the light at the end of the hall, and I knew the elevator door was open. I also knew that by the time I got to it, the doors would close and I'd have to wait for it to cycle back down again. Well that's just great. Even though our building is only eight floors, it takes like ten minutes for that elevator to get back to the first floor.
But wait...as I got closer, the light remained. Maybe the person in the elevator heard me open the front door and was holding the elevator for me. As I stepped inside, I saw that there was indeed a man holding the "door open" button. Well that was nice of him. See, I knew there were still some decent people in the world.
We nodded at each other, and he let go of the "door open" button. After a few seconds, he pressed it again. No one else had come into the building. Then he pressed it a couple more times in rapid succession. I looked over and pointed to the "door close" button.
"Oh. thanks."
He wasn't actually being nice. He was just stupid.
