I remember some little kid in hgh school. Under 5 feet tall. One of the football guys, over 6 feet tall, over 200 pounds. Tackle. Tried to take the little kid's lunch money. The little kid told him 'you may win, but you are going to the hospital. I'm gonna climb up the front of your shirt, and mess up your face. The cheerleaders wont be able to look at you without crying !'.
He backed off. And I followed him. I told him over and over what I was going to do to make him feel pain.
Later on we became friends and when that gang threatened a friend of mine. I told the cops the football tackle had changed and he wasn't with them anymore. He didn't go to prison, they did.
Yeah, I'm over 6 feet tall these days, but I was the smallest kid in that school back then.
