Thank you, @Yaowen and thank you, @divine1966!

I agree that these kinds of people are not emotionally well, and that they likely project all their own suffering and personal anger onto others by lashing out passive aggressively. I believe their dysfunctional way of communicating is much more about their own internal state than about another person, like you said, Divine.

I feel very sad for them too, because they must be very dysfunctional in their own lives and clearly cannot communicate their feelings or emotions properly or in healthier and more productive ways. All they end up doing is creating a toxic relationship dynamic, resentment and anger to all the individuals whom they offend through their passive aggressiveness.
