I will also never forget the first time I thought I was tough enough to stand up to my dad either. At about 16 I was starting feel pretty froggy I guess, so I stood up to him one day. I did not think back then someone could just hit me dead in the chest and double me over as I thought I was a stud after a semester of weight lifting. I remember it clearly. Dad, "Are you standing in my face right now?" Me, "Why yes I am." Me a tenth of a second later sitting doubled over on the floor holding my chest. Today I am 34, my dad is 57 and I am still not sure I can take him after that one confrontation. It was the only time he ever did anything besides bust my butt, but I am pretty sure I was being a little **** and deserved it.
I have 2 little girls now and I hope I am good mix of old school and new school. The biggest thing I try to do different is never punish them when my temper is to high, and I have never spanked out of anger to date. They are 5 & 8. Still a long way to go as teenage girls scare the hell out of me.
