Same here. And 90% of the time you were friends with your opponent a week later.
95% of the fights I got into in school were with one of my two lifelong best friends. Those were pretty much forgotten in a matter of hours. We still get into some pretty heated arguments over things every once in a while.
I went to a rural school all my life and grew up with pretty much everybody there. We were pretty isolated so things needed to be settled pretty quickly.
