Hmm...My worst experience with a school-kid was when we had a guest speaker at our school who was talking about how school bullies had a far-reaching effect on people's lives, even past school-years. One person who, uh, didn't exactly share that opinion spent the rest of the day mock-apologizing to me. Eventually, at lunch, I got fed-up with him. He hugged me from behind while shouting my name and pretending to cry, so I leaned my head as far as I could forward, and then swung it back into his face.
Then I ate my soup.
