That’s how all fights should be. Not yelling Worldstar a million times while a crazy woman is screaming in the back. Just two adults handling their differences and then having the courtesy and respect to hug it out.
My group of close friends (about 8 of us) have used this tactic since we were kids. If 2 people were pissed at each other or wanted to fight it out, we just let them. We would monitor the fights and at the end we hug it out. I think fighting is a completely natural instinct and could be used in a positive way. Nothing wrong with 2 guys wanting to fight and letting them do it in a monitored environment. None of us ever got seriously injured and nobody ever refused to stop fighting when we asked them to.
