Could you elaborate on that? It's the first time I see such a sentence. It's more than lack of communication, you see. Have you ever heard of what's it like to live with a narcissist? I understand now. Does it mean that you agree with me on the current matter of names and words? A skilled orator can use being nice - or, rather, non-confrontational - to the best of their advantage. People shield up when they hear something that sounds like an assault on their integrity; as such, appearing nice - that is, not disturbing others' worldview, but rather shifting it inch by inch through careful questions and statements - might be a weapon more powerful than an witty rant, in some situations. Not that you have to be nice to people at all times if your point is to please them or don't let them frown from you expressing yourself. I mean to say that it's not all bad.but don't feel like I swung my leg too far when hit by the hammer. ;)
My mom can't communicate either.
Salty, acerbic - I was stretching the metaphor.
But I don't think it's necessary to outright "be nice."
