I'm a little angry at my sister. I'm not very angry because I am accustomed to being angry with her. I told her in a message that I was upset with her. All three messages I sent ended up being funny to me! Strange, right?

Each message I sent started with anger and finished with laughter. I don't know how she felt, but that's how it was for me.
