I remember being bullied in primary school. It's not exactly a good feeling to wake up every day pondering on what the others are trying to do to make you feel miserable. Luckily, I wasn't nearing Self Delete but seriously, the worst years of my life were year 3 and year 4 most definitely. There were two kids who especially loved to bully me; one of them died in a car accident nearly two years ago, so remember kids, DUI is a bad thing. After those years things have been relatively mellow, but I'm especially nervous ever since.
Also, the worst thing about bullying is that if the bullied person transfers to somewhere else and finds someone weaker and/or even more lower ranking than him, he will become one of the worst bullies ever. I'm speaking from experience.
