PP here. I honestly believe it is NOT an Asian thing. Lets face it, what we read here points to insecure MIL in a p*ssing contest with disinterested DIL.
My MIL is this way, and I don't engage. I don't have anything in common with her, never did anything to her, don't need anything from her, and she is disrespectful to me. So she can suck it.
MILs like this are threatened but he new woman in the family. They should be embracing the DIL, not in a p*ssing contest with them. But some old farts do not like "different". Her problem, not mine. Imagine what the world would be like if we were all like MIL? God help us, really.
