Did your parents expect all children to act like little adults and to prioritize the emotions of actual adults?

Ever since I can remember, I've had to shove down all my emotions to keep my parents happy. I do it without thinking, it's as natural as breathing, it's just how I was conditioned to exist in the world. But, not everyone was raised this way.

This weekend I had to hear my mom complain about a friend that I invited over as a child, almost TWO DECADES ago, who "made things awkward the whole time she was over."
How did she ruin everyone's weekend? She rightfully got upset and sad when my cousin called her fat, and no longer wanted to do the activities we had planned. She was far from home and had just been bullied by a stranger. I understand why she was so upset! But to my mom, this was like the worst thing that anyone could do.

My mom expected this child to regulate her own emotions, deal with the conflict on her own, and then just "get over it." My mom, the adult in the situation, should have talked to my cousin, made her apologize, and tried to repair the situation. But, during our conversation, she repeatedly stated that I should have done these things so the whole weekend wasn't "awkward for everyone."

How are you, as an adult, going to let a child ruin your weekend? And how are you, as an adult, going to be upset about this event two decades later? I cannot understand it. Not even a little bit.

Did your parents act in a similar way? Did they expect you to be little adults for your whole childhood, or emotionless robots?
