Andy shares a great story...
Mine is embarrassing to the other person more than it was to me. I am a guy who knits. And usually this in and of itself stimulates reactions and comments where I am convinced a woman doing the same thing would be ignored. The best one recently was at the Champlain Valley Fair, where the woman said, "Some of the greatest knitters in the world were men," in a voice that was as if she was talking to a kindergarten child. But I digress.
The best story happened at a local movie theater where we go to see the Live Metropolitan Opera HD broadcasts. I knit before the show and during intermissions. It's always a sock.
I was standing in the lobby with my husband and knitting and chatting. This woman walks over and stares at me. I'm kind of used to this and I just wait for the questions. But instead, she said aloud to no one in particular, "Well, well, well. I've always heard that there were male knitters but I've never actually seen one before."
She never really engaged me in conversation. It was more like I was an exhibit at the Knitting Zoo: The Elusive Male Knitter.
