When we broke for lunch, she came over and said to me, "I just realized who you are. You're in my knitting group." Of course, then I realized exactly who she was.
It's always hard to recognize people out of context. And I haven't made it to knitting group since I moved.
I suspect it would have amused other people had I said, "Oh, I didn't recognize you outside of the police station." (Yes, my knitting group meets at a police station. They have a nice community room.)
