I had a couple classmates that pretended to be vampires back in elementary and middle school. They’d pretend their Koolaid was blood, complain about the sunlight, and bite their friends a lot. Not enough to draw blood, though. I haven’t kept up with most of them, but one guy is a teacher now. He seems pretty normal.
A kid I went to school with named Adam told us at lunch he was an android when we were 12 years old. He was new to the school and said he had to go to new schools every year so people wouldn’t find out his secret. He claimed he felt no emotions or pain and was a genius.
A kid named Steven asked him to prove it. Adam jabbed his thumb with an unfurled paper clip and made himself bleed, then put salt on it without showing any pain. So Steven stabbed him in the hand with a fork and he screamed, cried, and ran to the bathroom. He wasn’t an android. Steven got detention. Kids are weird.
