Aarrrggg!!!!

So....I resurrected a shawl that I started a long time ago that had been sitting in the bottom of my knitting bag. I knit two very, very long rows and realized I had made a mistake at the beginning of the first row. It's a mistake that cannot be fixed by going back under the stitch or anything like that. Consequently, I am tinking back all of the two very, very, very long rows to fix it. Aarrrggg!!!!!!!
