Well, some people don't have a sense of humor.
I went to the store and when I was getting checked out at the register, the 2 cashiers were picking on each other. So I teased them by saying, "Ok children." One laughed but the other one got upset and said, "I am probably older than you are the same age." She said it kind of hateful. The other cashier gasped at her. I told them both, "I always say that to people no matter if they are older or not. It is just my sense of humor!" The other cashier just walked away from me and the one that laughed finished waiting on me and I left. Think the cashier that got mad was new and I bet she will get a talking to later.
