Cross stitch: Annoyance

I hate when I'm working on a cross stitch piece and I realize I put in an extra stitch in the pattern like 50 stitch ago. It means taking out way too much to fix it. Then my thread knotted, snapped, and I wound up having to take out even more stitches to deal with that mess. Sigh. If this wasn't the only piece I brought with me to work on while I was with family, I would put it aside until I'm no longer annoyed with it. I knew I should have brought something else as well.
