Probably years ago, I usually don't have much physical interaction with anyone else except for my family. Like, I do go to stores and such but that's pretty much it.
About five years ago at a Christmas party, Had to deal with a drunken fool that did not want to leave he just wanted to fight with the ladies there.
He did leave with the police at the end.
Wasn't much of a physical fight if we did not even touch. Was back in College, End result was that it was a couple of us that we see every god damn day for hours in a classroom and we had each other nightmares. Did not last long and mates again under a week LOL
I confronted my bully in high school. She and two of her 'thug' friends corned me in the girls restroom. The bully (Crystal) kept shoving me while her 'thug' friends were laughing. I told Crystal to get her hands off me. She said 'make me'. I finally snapped and punched her in the face. She hit her head on the sink as she dropped to the floor. Her 'thug' friends ran out of the restroom. I went to the school Nurse and told her Crystal was lying on the floor in the girls restroom and she needed to go check on her.
I then went and reported myself to the Principal. Crystal and her 'thug' friends were called in and asked what happened. They all said the she slipped in the girls restroom and hit her head. I wasn't about to say anymore.
Not proud of what I did but it did stop the bullying. Never have hit another person after that.
I had fist fights in elementary school and once in high school. I don't do fist fights because I don't want to get convicted of assault with a felony. Court lawsuits and lawyers cost volumes of money.
