I work for a Pharmacy at a hospital in Canada.
Today, I had a "1 on 1" with our new manager; basically an opportunity for her to get to know her staff.
Part way through, she asked me about what music I liked, and in response, she listed a few "classic rock" bands like Queen and Pink Floyd. I jokingly mentioned how that was the kind of music I grew up with since that's what my Dad listens to. To this she said, "I know, I'm so old!".
I had no idea how to respond to this. She isn't old by any means (I'd guess ~30), but I didn't know if it was appropriate to contradict her, as that might have been seen as sucking up to, or hitting on her.
I ended up just kind of smiling and laughing to myself while looking away (I'm kind of awkward).
What would have been an appropriate response?
