My dad laughed at me since I was a kid?

Hello, your father mocked the incorrect way of educating children. Such behavior can easily make children feel inferior, let alone beat them. Many parents don't know the disadvantages this kind of education will bring, and always think that mocking and beating children can make them more upward, but this idea is wrong. I suggest you have a good talk with your father and tell him that this is wrong and will make you feel uncomfortable. I'm sure your father will feel uncomfortable, too
