Sometimes it's good to release your power level a bit. I was reading a manga during my break once. This girl I work with asked me why I was reading a book backwards. I told her it was a Japanese comic book and that they are printed in a different direction. "Oh, like Yugioh? Don't you think you're a bit old for stuff like that?" I turned the manga around and showed her the page in Hellsing where Seras shreds the other vampires face against a wall. She's afraid to talk to me now.
