Many children grow up believing they do not have the right to make a mistake and be responsible for it. The parent spills her tea and it's an accident, something that happens by chance and results in loss. There's a big psychological difference between a mistake and an accident. There is blame assigned to the mistake. Some people deny you the right to change your mind or to make a mistake and be responsible for it.
Many people grow up believing they are capable of being more than human.
They talk to others as if they have never made a mistake. For them, to make a mistake is to be less than human. These people were raised by parents who shamed them every time they made a mistake. Now you're an adult with your own children. Your parents, brothers and sisters shamed you every time you made a mistake.
