He was a fat kid in elementary school. He bullied other people because of his low self-esteem. He thought kids were laughing at him because of his weight, but he was just paranoid.

Twenty years later, I attended mass. As I was going home, the priest called me and said it's been a long time. I didn't recognize him immediately. It was the bully. He lost a ton of weight and he's now a very kind guy.

He told me that he has had an itch on his back ever since he was a little kid. But he was to chubby to scratch his own back. This made him irritable and he unleashed all his frustration toward other people. When he was in high school, he bullied some guy as usual. It turns out that the guy was a psycho. Psycho boy chased the bully with a knife. Bully was running for years. He got tired and finally apologized to the psycho. He left him alone and the bully was just sitting there. He instinctively tried to scratch his back, but he finally reached it this time because of all the weight he lost running.

It was the most satisfying thing he experienced.
