history: I had a coworker at one job that just would NOT stop talking. She would hold you for 30 minutes, just chatting away about nothing. I've got a coworker with zero social skills_comma_ and it's driving me batty. She can't seem to tell no one wants to listen to her talk for 30 minutes straight.
current: Oh man, I've definitely had a few coworkers like that myself before. What does she even talk about?
next: If you make a comment on anything, say cats, she'll go into a monologue about everything she's ever learned about a cat (most of it wrong).
