There isn’t any particular ruling. As long as you can do it and it pleases your father, you should try your best to make you father happy and satisfied all the time. But if this hurts you or delays you from your work or study, you should explain to your father in a nice and polite way.

My brother’s son always cries and ask me to play game with him. He is three years old. If I don’t play my father gets angry at me what is the ruling?
