What should I do if I meet an eccentric mother?

Find a chance to talk to mom. Communication.

Speak out the sadness in your heart, and let your mother realize that what she has done is inappropriate and will pay attention to it in the future. Don't treat your brothers and sisters badly just because your mother is partial. On the contrary, you should have a good relationship with them, so that mothers can see that their children respect and care for each other.

Every child is so sensible and lovely that he won't be too partial. Don't worry about your mother's partiality all day, focus on meaningful things, shift your goals, downplay this matter, and do something that makes you happy, so that you won't feel too bad. Finally, be more tolerant and understanding to your mother.
