I'm always pretty self-conscious about pulling my knitting out in public, I don't know why! I have done it a couple of times though, in the waiting room or at the airport, and no one's ever said anything to me about it. I did see a lady knitting at the airport, and since I'd never seen anyone knitting out in public before, I got so excited I wanted to shout, "Ohemgee, I knit too, let's be best friends!" but I held my tongue. Lol.
