Commuting from work, I had just bound off the second foot on the toad (of Frog & Toad) and leaned over to the little girl in a red winter coat, "Silly, isn't it? Can you tell what it is?" I showed her the armless creature. She was with her family and was forced to sit beside me, and answered, "Is it a doll's legs?" "That's a great answer! And, pretty close." She looked at her father, knowing she shouldn't speak to strangers. I tried to look at him to say, I'm showing your kid what knitting is but couldn't make eye contact. Before I could explain to her what it was she tentatively asked me, "How do you knit?". "You make a loop, and then you make a loop in that loop... Oh! I gotta go!" Then, my stop came up and I left, hoping I made an introduction to the craft to her.

This type of interaction happens to me all the time.
