Oh banging one's head on the floor reminds me of a story that amuses me for some reason even though I know I was being made fun of.
I was banging my head on the floor in the dayroom of a mental institution (was within my first few days in one ever, for suicidal behavior). And... this other kid came up to me, and he said, "Are you a head banger?"
I had really bad language comprehension at the time, so I said "I don't know." (I think that was my stock response to questions I was too afraid of getting wrong to answer.)
And he said (to everyone) "Hey look at this girl! She is banging her head on the floor and she doesn't know if she's a head banger!"
I still don't know why I find it funny, I should be annoyed at him or offended for making fun of me or something, but it still comes back to me as an amusing memory rather than an offensive one.
