If I was her boss I'd be "standoffish" too! My parents were also that way, by the by – they called me a slut for holding some guy's hand and kissing him when I was in college.
Oops did I say that out loud!? Wow, I'm a bit surprised, and I can be a good bit abrasive at times. But I can imagine that based on how it's written, for the OP, she probably wouldn't have said that the first hundred times the boss was sexualising his daughter. Maybe she was a bit harsh on her retort.
By the sounds of it, she was tired of hearing about the sexy perfect blonde daughter, but one things for sure. She made an impact and probably won't hear about the daughter for awhile!
@altschmerz yeah, that can be a touchy subject for some families. It's an unfortunate word to describe their view of the behavior too. I think it stigmatizes sexuality which can already be uncomfortable to talk about. Opinion aside, hopefully she learned a lesson on etiquette.
To say that thing about being a whore was totally unacceptable and unnecessary. Why to be so aggressive?
