In my situation, the person isn’t worth my words or effort anymore all they get from me in silence.  But others can take it that if you can’t be bothered to give an answer or response. You aren’t worth keeping around. I don’t agree! Everyone deserves a response. No response just means you are thoughtless and inconsiderate !Look, introverts sometimes let it linger. Because they don’t have the energy to return an “appropriate” response. There’s no reason to make us feel more guilty about this than we already feel. We’re here, we love Grinch yall realize I’m gonna snap one day right Christmas shirt, and if you’re a real friend you know that.
