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.
Yeah, I thought for sure he would have outgrown it by then, too. He copped to making up the archangel Michael bit, which surprised me, but he was keeping the dream alive as a vampire.
