People can be really strange.
I had a coworker asked me to loan her $500 years ago (before the pandemic!). I didn't even say no, I just asked her what it was for. She got upset even at that, said I should just trust her and said that because we worked together for 5 years, $500 was nothing since its just $100 a year (wtf?!)
She then ignored me for weeks, until she realized I didn't give a crap and just ignored her as well. Suddenly it was all a misunderstanding (my misunderstanding of course). She just sent me a message this week "May I ask why you stopped talking to me?"
Some people are just blind to their actions, they've learned to project.
