AITA for being “cold” to a newish coworker?

Sounds like she brought it on herself. Women do get hit on more for sure, but I’ve also run across women like this who think every guy in the world wants them and that’s the only reason any man is talking to them ever.

They are toxic people and best avoided. They are also the ones most likely to report you to HR for a normal work interaction. So yeah, definitely stay far far away.
