I hurt myself. 
I got into the Groove, the Mojo of Coming Together, the Blessed Zone of Creativity. I was working on the school auction quilt, and I had it all falling into place. What? That twinge in my shoulder from sewing for 2 hours? I'll stop after this petal. Some time later... hmm my neck is getting stiff. I did just stop for dinner, um about 90 minutes ago. Oh, some chair stretches should help. Wow, its ten o'clock. Nope it's ten thirty and.. oh I hurt. When I woke up at 5:30 am because my neck was yelling at me I realized just how far I'd overdone things. I have been expecting this to happen since I stopped yoga. Now, I am going to see if I can sneak into a level one class this morning and try and put my shoulder back where it belongs... 'cause I still have more sewing I want to do...
