My mother tried to ground me a lot. This typically resulted in me disappearing for a few days at a time (with all the stuff I needed to still make it to school, and I'd find my way there and do my work). My dad, on the other hand, was very difficult to make angry, but once I did, he and I were taking swings at each other. I'm convinced his way was better. I can sneak out pretty easily, I can find where you hid my games really easily, and most of the time, you'll never know I did it. It's harder to dodge a punch (or overpower a guy you're giving 100 lbs to in a grapple) and if you do, he'll know, and come back with another one.
