Well, lots apparently. Last Thursday, I had a toothache. I went to work late, after paying my dentist $50 to agree that yes, I had a toothache. There was nothing to do but let it develop. Of course, Friday I worked at my other shop, and was very busy all day. When I got home, the toothache had worsened to a constant, awful pain. In fact, it was so bad, I couldn't knit. That's when I knew it was serious. I made it through a very busy weekend, knitted not at all, and this morning, I had a root canal. I still haven't done any knitting, and my mouth still hurts. I am assured that it will get better soon. I'll let you know when I'm knitting again.
