They try to match your interests/attitude/hobbies/etc in an attempt to get you more interested in them, and ultimately, to manipulate you. One of my exes seemed to do this to an insane degree (right down to using the same brand of ghee to cook with, despite the fact that 95% of Americans don't even know what ghee is), though it's possible some of these were genuine coincedences. Either way, it's a big red flag particularly if you have esoteric/fringe beliefs/interests; women rarely think outside the cultural norms like that.@FlexpertHamilton what is personality/lifestyle mirroring?
Corporate simps also personality mirror their bosses, though that's more about sycophantism than anything.
