Also to further clarify, since some of you are assuming that the spanking was intended to punish him for failing. First off, I never did spank him to begin with because at the time I was upset and I will never spank my child out of anger. Secondly, if I had spanked him, it would have been because he lied to us and attempted to deceive his teacher by forging our signature. Furthermore, just because I'm a proponent of spanking doesn't mean that I physically abuse my children. I've never cursed at my children, or hit them with an open hand, or yelled at them to belittle them. But if they misbehave they will get spanked on the bottom ... and yes, spankings can be effective if used the right way.
