My mother is a minor. Every time I go to dinner, I will forget me and only take my sister. When my mother remembers, she will call me and let me go alone.

Ignore her when she is talking to you. Later, I washed my underwear and washed the dishes myself. No matter how much she scolds you, ignore her. Women are most afraid of being angry with others and being ignored by others. Don't go after eating like this. Get something to eat at home and never go back when you grow up. Since you are partial, let your sister provide for her old age.
