I have a bad father. He often takes it out on me and my sister and finds fault with us. For example, my sister stays in the room for a long time.

It's good that you ignore this. After all, you will meet all kinds of people in society, and your father is just one of them. But the hardest part is your mother. You can't imagine how much she put up with for you and your sister. It is estimated that if it weren't for you and your sister, she wouldn't have worked so hard to maintain this family. Children in single-parent families all have psychological defects. I just can't express it in words. One day you will grow up and become the pillar of your mother and sister. At this time, you don't have to be bound by him. You have to refuel.
