Well, I am not sure if this is appropriate but here it goes. I am a Middle School teacher. One day I left campus to go get lunch on my lunch break. When I came back to school, I noticed a bunch of elementary kids (maybe 2nd or 3rd grade as they were pretty tiny) riding bikes on campus. When I got out of my car, I said, "school is still in session, so you will have to ride your bikes around here later and can't be on campus." I was not mean about it, but just wanted to let them know. This one tiny little boy rode his bike really fast past me and yelled, "fuck you, lady!". I was so shocked that all I could say was, "What?"
