How to convince dad?

When I came home at the weekend, my mother and I complained about my father's mistakes and cried, which gave me a chance to talk about my father and let him change.

It pains me to see my mother crying like this, but it hurts me to convince my father. Because I feel embarrassed, it is the most difficult to convince a person to do such a thing, and it is also very embarrassing to be rejected in the end.

I couldn't sleep in bed that night and thought about it again. What am I supposed to tell my dad? Or how to convince my dad successfully?

"Dad, you can't ... you have to ..."

This routine has been tried, and it is useless. If I use this routine again, it will not work. I went online to find relevant information. The general idea is as follows:

Dad, my mother told me that she is living a miserable and unhappy life now. She doesn't know how to please you. You are not satisfied with anything. She wants you to respect her and tolerate her.

She knows that instant noodles, ham and sausages are not good things, but are used for worship. She said she could buy a little at a time. I hope you can be tolerant every time you see her buying those, and don't talk about her every time and show unhappiness.

She said, now that our children are all grown up and not at home, only you two can live happily as before. She hopes you can be considerate and considerate of others as before, and she will buy less things that you don't like.

The next day, I still didn't have the courage to communicate with my dad, so embarrassed.
