Sitting in one spot for along time irritates my toe with the missing nail, too. When, on Wednesday, I go to the dentist to have the fake tooth part glued onto what's left of the real tooth, my toe will probably still be annoying me. I'll be sore in two extremities. (Yes, I think of my head as an extremity, though that is a decidedly unconventional view.)
My brain is fizzling again. The day was a bit warmer than yesterday, and my brain has already endured its seasonal quota of heat. But September is a mere ten days and some hours distant. Only one month until the equinox. I might survive, as long as I don't have to think too much.
