Hello, I have been reading the thread and your situation seems terrible to me.
I have a pretty conservative view of almost everything, I'm not opposed to progress, but I think a lot of things were better and easier when I was younger.
What I cannot do is try to impose this on the people who love me and who have a certain dependence on me.
When everyone has the same vision, it's hard enough, and I've had arguments at home and my sister-in-law @Tere the same. And, to give an example, my situation is like when I start a diet, I open the fridge and take an ice cream. My wife sees me and scolds me. Yes, I know that I am on a diet, that ice cream is not good for me, I know that my wife is right and that she does it for my health but it annoys me. It would be a simil with the belt in my house.
In your case, with another vision of things, I don't understand how your mother can do that.
