I was 16 and my parents had to go away for the weekend. I told a couple close friends that we could hang out and drink some beers at my place. Word got out because high school and a larger group of people showed up. Most of these guys were my friends but a couple of them were there because of the group I hung out with. One guy that I never liked thought he could take advantage of me. I'm a quiet and non confrontational guy. Everyone knew that. He tried to a***e that trait. He stared eating my food, tried smoking in the house and was pretty much being his d****y self. I told him to get out of the house and he got c***y. He figured everyone in the house had his back over mine (he'd started fights and let others finish before). We were face to face at the top of the stairs that went to the entrance. After a lot of yelling I Sparta kicked him down the stairs. Ran down and punched him in the face then picked him up and threw him out the door. One of the most rewarding experiences of my life. Bullying and teasing at school went down by at least half because everyone saw it.
