Hmm, I think in my case it was the nuns beating the @rap out of me for 12 years.
I think from grades 2-5, I averaged 1 paddling every 2-3 weeks; sometimes another switching when I got home too, mostly for fist fighting, sneaking out of the class, throwing pine cones or dirt clods, leaving the school property during recess to go into the woods, and most of that time with my good friend and neighbor....we played extremely rough and would fight a lot when one hurt the other pretty good whether at home, on the bus, or at school.... Army brats, and the teachers and parents just couldn't get over how much we love to fight one another. (Good training)
