I was talking about nothing with one of my co-workers and she made a little joke about something, and I distinctly heard someone say "Good one!"
But I looked around and it was just the two of us. So we kept chatting and she was talking about how one of her library classes was dumping a lot of pointless work on her, and I heard "But you always do so well with those projects. You're so smart and such a good worker!"
I looked down. "Was that your shoes?" I asked amazed.
"Yeah." She replied, maybe slightly embarrassed. "They offer a lot of support."
