The only time I did was when she was about 15 and she was talking to me while I was watching something on TV so I wasn't paying attention. She got angry and kicked me hard on the shin. I don't think she meant to do it that hard but any way I stood up and slapped her face. That's the sorry story of violence in our house.
Out of curiosity, do you consider yourself a better parent than those who spank? (I assume so, considering your wording of your first sentence.)
The reason I ask is because you hit your child in the face out of anger, and my father spanked my bottom as punishment but he never did it angry.
