I think quite the opposite of what you say. Many parents can only give from what they received because they did not learn anything else.

I have a son, I was also somewhat harsh in character with him, but not to the same extent as I was treated. But I did hold my frustrations for many years until complaining helped me to get out of so much resentment.

It helped me a lot that I read a lot, studied a lot, assimilated that we take our frustrations out on others and that should never be so. My son and I are good friends, thank God.
