Today I was walking past some students who were still making out right after the bell rang to signal the end of break. The conversation went like this:
“Make out time is over, get to class.”
“Bitch” (this was kind of muttered as I was walking away.)
I turned around and said: “I am not a bitch. I am a very nice person,” and then I kept walking.

I like that my instinctive response to being called a bitch is no longer shame. 🙂
