Knitting while seeing a professional play? In the front row? With metal needes... I agree with you all, no way.
But I have to say that there is one kind of live performance where I always bring my knitting and it saves my sanity. I'm talking about children's recitals. You know, the kind where 200 children are in the production, and your child or children are on stage for about a total of five minutes, and you have to sit through the rest of the two-hour show smiling bravely while everyone else's offspring mangle music charmingly? And you have to do that about eight to ten times a year? And you have to clap with enthusiasm and tell your kids how much you enjoyed being there? Knitting saves me.
