When I was in middle school, sometimes I would wear a bandage wrapped around my arm, even though I wasn't hurt, and then suddenly grab my arm, and say "Gah! ...Damn! My arm is going wild again..." raising my voice, because I thought it was cool. And then I'd say something like "Those bastards must be close, again..."
When my classmates asked me, "What are you doing?"
I'd reply with something like, "Hah, I guess people without an evil eye (the third eye that I had in my own little delusion) wouldn't understand..." and disappear to somewhere unpopular.
When I remember suddenly standing up in the middle of a test and saying "Even during a test... those persistent bastards!" and running out of the room, I want to die.
In my Judo lesson, I grabbed my arm like it was in pain in the middle of a match and said to my opponent, "Gah... ahh... get away... If you don't want to die, hurry up and get away from me!!" The gym teacher apparently knew what kind of student I was, and that match ended in a "no contest".
Every day was like that.
Of course, with such a painful character setting, I was often called out by groups of deliquents, saying things like, "Show us your evil eye!" But even so, I'd reply "You're nothing but a bother... now disappear" and make them angrier, sometimes to the extent of being put in a sleeper hold. But when things like that happened, I would act like my arm was in pain and say "You bastards... I won't forget this...", acting like something posessed me for a moment. I'd just buy time like that until our break time was over. The time between classes was fine, but lunch break was a nightmare.
