25 years later, my perspective on things have changed a great deal. The rod or tsinelas is no longer the evil thing I remember it to be or what some child psychologist would tell you. Just remember these things I have learned:
1. Never do it in anger. They feel it and they are going to resent it.
2. Explain why you are do it, so they won't think that you just do it for kicks
3. Do it in private, keep their dignity.
4. After the crying, hug them and tell them that you love them.
