This woman I know is friends with some of my friends. However, she is almost always passive aggressive and rude, though sometimes she’ll be polite or ask things about me to get to know me.
She asked me why I even want to talk to her and when I say anything, she says something like “Nice thinking skills”, “How did you figure that out, Sherlock?”, “Just fucking great!” “I hope you die and I never wanna see you again”.
When I’ve asked her, she says she’s fine though and nothing happened to make her this way.
I’m very sarcastic and it’s playful banter in my family. There is a feeling of inclusiveness sometimes. But even we have a couple rules; no threats and you don’t pick on mom.
But that last example you gave crosses a line for us. That’s not playful.
