I got a weird upside down version of this. At home, my father's behaviour was never to be questioned, because he was never wrong, and if he was, it wasn't his fault, someone else made him do it. At the same time, he was habitually cruel about other people. He could find fault with anyone and it was always spiteful. The rule was that we had to agree with him. Now I understand that was a coping mechanism, albeit a poor one. But I have to hold up my hands and admit that sometimes, I voiced those opinions to other people outside of the home, and was frequently ostracised for it. I once told a girl on our street that I thought another girl on the street was fat (my father's description of her, a 16yo girl he didn't even know). I think I thought she would agree with me and it would make her be my friend. The opposite happened. All the kids on the street shunned me. I'm so embarrassed looking back, but at the same time, I know that I was immature and stupid and that my social skills weren't developing normally. How could they? I also know that a lot of people actively disliked me when I was a child/teen. I suspect that I was awful; overly opinionated, neurotic, deeply anxious, judgmental, controlling, mentally ill.
That aside, I've spent the weekend playing a new game I'm calling stupidity or spite, in which I keep remembering things my mother has done, which I blamed on stupidity, but I'm suddenly asking myself if it wasn't stupidity, it was spite, and I just didn't want to see it. As an example, my eldest child has some difficulties, caused by a very traumatic birth. For ages, every time I saw my mother (and she would always do it when other people couldn't hear) she would say what exactly is this issue she's got, I just don't understand. I would explain. And the next visit, she'd do it again, until eventually I ran out of patience and said I didn't understand why she kept asking, because I'd explained it repeatedly. I wasn't even planning to say it, it just slipped out. I remember she just sort of froze in her seat like a deer in the headlights. She didn't apologise or anything. I told myself that the not understanding was genuine, but now I've started to wonder if she thought she was being clever, that it was in some way a dig at me. IDK. But it's not kind, is it?
