We were not allowed to contradict our mother. Self-defense was not allowed, even if she read our minds incorrectly. She always believed what she thought was true. This is why I made a very big point of teaching my kids that no one knows themselves better than they each know themselves. Period. No matter what.
To this day, it amazes me how some people make up stuff about other people in their heads, and believe that what they made up is true! I say if you want to know something about someone, simply ask them. Figuring one knows the answer without asking is the stuff of soap operas.
I'll give you an example. When my mother died, she had a large collection of scarves - accessories, not winter wear. They were beautiful. She always tried to get me to wear them, but I felt like a pig dressed in a tutu in them, so I refused to do so. I am just not a scarf person, and don't talk to me about ruffles! I do not like wearing scarves. It's a trait of mine - it doesn't mean I was strangled in a past life, so don't go there. People have!
When my mother died, I took 3 small framed prints and a 3" stuffed terrier, none of them valuable. The rest, I told my sister she could take, because I'd always planned to do that. She deeply cares for things that have sentimental value to her, and lots of things do. I was not about to get into arguments over possessions, especially since we both like the same things.
She hired a moving van and moved a lot of stuff to her house in another state. She discovered one scarf was missing. She stewed over it for 2 full years. Then she called me and said that I had stolen the missing scarf. No, I didn't. I pointed out how I have a lifelong aversion to scarves, and wouldn't want to own no matter what. She said, well you must have thrown it away. Please, with her guarding my mother's stuff like it was the Hope Diamond, I didn't have a chance to toss anything, and wouldn't have anyway. She wouldn't let me help her pack, take stuff to Goodwill ... nothing. She still thinks I am thief.
The entire situation was frustrating, but no more so than the many times my sister has decided she can read my mind and is right. She gets it from my mother.
