I was waiting for an elevator after working late one evening and, when the doors opened, there was a cleaning cart. You know the cart. It's the one the cleaning people use that has all their supplies on it. It was all alone in the elevator.
As I got on the elevator, I smiled to myself because I knew that, somewhere in the ten story building, a cleaning person stood patiently waiting for their cleaning cart to come back to them. There are four elevators, so all they could do was stand there on whatever floor they were on when their cleaning cart made its great escape and wait for it to return.
I was so amused by the cleaning cart on the empty elevator that I didn't notice that I got on an elevator that was going up instead of going down. When the door opened two floors above my floor, there stood the cleaning lady.
I said, "Hey! Lose something?"
She didn't find the whole situation nearly as amusing as I did.
