I am a high school student, and I have only one holiday every week. I don't know why my mother always finds a topic to scold me every time I go home every week.

It is possible that she seldom sees you and doesn't know how to talk to you. She can only pick out some shortcomings in you like her elders, and then take it as a topic. This is also an alternative concern. Only in this way, it is easy for you to quarrel with her, and then the atmosphere begins to be tense, which leads to your failure to return to that warm atmosphere and endless cycle. She just doesn't know other ways to get along with you. She is worried about your life when she is away. The next time she starts cursing, you can try to answer her in a calm and tolerant tone, or try to find a topic to joke with her.
