Hello; Interesting thing about small human beings. I had to break up fights as public-school teacher. I learned to be ready for an "errant" punch coming my way when i stepped into the middle of a fight. I also learned to gauge when the fight was serious and when one and often both combatants really wanted to have it stopped.
At the first school I taught, a high school, one of the coaches would put boxing gloves on the two caught in a fight. Bet that is not allowed now days anywhere.
Also, at that first school I found two girls fighting behind the school. Rather it was one very big girl whaling on another girl by the time i saw it. No crowd around, just the two in a lonely corner. I went up and grabbed the bigger girl's arm as she reared back to throw another punch. She just shook me off and went back to slugging. The fight was over by then anyway. The other girl was done.
The big girl was sort of a gentle giant most of the time. The girl who got a good beat down was an offensive loudmouth known for starting trouble. Guess she started on the wrong person mistaking a general gentle nature for a pushover. For what it is worth not one slap involved.
