Knitting Intermissions

I knit during the intermissions of Sharks games. I think I have mentioned this before. Well, last night there was a lady sitting in front of me, also knitting! I was engrossed in my knitting and did not notice but my friends pointed it out. I then leaned over and admired how fast she purled (it was very very fast) and then my friends teased me that I was cheating. Ummm, how does one cheat at knitting, exactly? Anyway, I thought it was cool that there are other intermission knitters, was amazed at the coincidence of one sitting in front of me, and of course, was too timid to say, "Hey! I am knitting, too!"
