I had some arguments with my mom before, such as, when she invested in stocks, she just guessed and listened to the radio, or watched TV. And then I asked her, if she knew what P/E ratio was, so that she could at least use it as some rudimentary guideline, she said she didn't know, but she just bought stocks on hunches. I then asked her, which stocks are you holding? She said, "Why should I tell you?"
And I think since about that time, she thought her way should be the way, and my way, which is to understand the company well, know what its earning power is, what the products are, is not the right way.
And then, she would see that I failed, in other things in life, and then felt happy about it. It was like, she felt she is competing with me now, and she has to be the one that is right.
One of the in-laws, however, just always gave her honey, or fake praises, so that she could have a lot of vanity. But when he doesn't see her, he really doesn't even care. He was merely to deal with her, and he also borrowed a lot of money from her. Since she got so much vanity from him, she actually very pleasantly lent money to him.
When I said to her, the work place is like a jungle, there are the tigers, fox, or wolf. Then she said, "how can it be a jungle? No! We are humans! We are civilized. You are talking all the gibberish." And then she talked to the in-law, and the in-law said, "It is worse than the jungle, because in the jungle, the tiger looks like a tiger, and the wolf looks like a wolf, but in real life, in the office, you really don't know what the people are. They may appear as decent, but they may be a wolf or fox, so it is harder." Then the next time, my mom talked to me, saying, "Tom (just an alias for the in-law) said, 'It is worse than the jungle'. Tom said, 'in the jungle...' and Tom said 'In the real world...'" and she pretty much repeated what he said like it was gospel.
In such situation, what can I do to bring back our relation back to a more normal situation?
