I got a talk with HR once because someone thought at some meeting I kept staring at her boobs. My literal answer was "er... what?", because I didn't even realize they were at that meeting, much less sitting right opposite me. I do however have a tendency of getting lost in thought and letting my eyes wander or fixate on some random thing, might be a plant, a chair, a random fixture, whatever... guess it could've been some boobs. 🙈🤷
If they had confronted me right after the meeting, I'd just apologize... but no, HR it was, and...
Any HR person knows that that's now how that works.
Since then, I make a point of carrying a pen and looking at that... just to avoid someone who I might not even notice is there, accusing me of sexually harassing them 🙄
