Perhaps this happened to someone like me, in a library very much like the one where I work:
I watched a man try very hard to compliment my manager one night.
“You look different somehow. What is it?”
“I’m not sure,” she said. “What do you mean?”
“You just look more feminine than usual is all. I mean it as a compliment.”
“Oh. Well, thank you I guess.”
“Hey wait, did you used to have a mustache?”
That was how the conversation ended.
