I feel guilty to this day.
I was the eldest of four and was horrible to all of them, but my little brother was the target of most of my nastiness.
We shared a room until I was 10 and he was 5. He had a snoring problem. It drove me crazy not being able to sleep so to stop him at first I would roll him over; eventually I would punch him in the head.
During that time I decided to make him piss himself in fear. I waited until he was asleep then hung a sheet over the ceiling lamp. This one backfired as I woke up to get a glass of water and saw this ghostly figure floating in the middle of the room and nearly died. He, however, had also woken up and thought “why did Jim hang a sheet on the light” and gone back to sleep.
Psychological torture: filled my little sister’s Barbie doll’s head with ketchup. Replaced it, waited until she was playing with it, burst into her room with a hammer and smacked Barbie on the head. She went hysterical. Hanged my other sister’s favourite teddy from my bedroom window so it was tapping on the window of the living room where she was playing. She went hysterical.
My brother once got busted for stealing chocolate cookies from the cookie tin on top of the fridge. Ever after I knew I could steal them with impunity because he’d get the blame.
I would pin him down, sit on his chest and do various horrible things:
Pin him down and fart on his face (an oldie but a nasty).
“Chinese water torture” - basically tap him on the forehead rhythmically for half an hour. It would indeed drive him nuts to the point of screaming and impotent attempts at violence, and he’d end up with a red lump where I’d been tapping him.
Pin him down and push marshmallows into his mouth until they came out of his nose or he threw up.
Stole and ate his and my sisters’ Easter eggs.
I used to bang all my siblings repeatedly on the top of the head with the soft part of the palm of my hand until they cried, then laugh. I did this because I could say “I wasn’t hitting them, I was bouncing my hand off their heads” and “I didn’t use my fist” when I got busted.
I stopped doing all this abruptly: one day when I was about twelve or thirteen I found myself sitting on the stairs not knowing how I’d got there. My brother was lying on the living room floor bawling his eyes out. I was concerned for him, and went in and asked what was wrong. “What do you mean what’s wrong? You headbutted me!” he cried. Sure enough there was a bruise on my forehead and an even bigger bruise on the top of his head. I must have butted him so hard it gave me minor concussion or something, because still don’t remember doing it. That scared the hell out of me, because despite everything I’d done, I loved my siblings, and it scared me what I might be capable of. I stopped bullying them forever.
