I am currently on a forced Sabbath from my computer. It simply wouldn't turn on Sunday. Viva la Mac! So it's at the shop, being admired for its beauty, and, I hope, being fixed. The good news is that it is under warranty and will continue to be under warranty for the next three years.
The bad news is that I was unable to finish my work. The other good news is that I have an understanding "boss."
Anyway, this update comes to you live from the Denton library. I hope to have the machine fixed and back in my possession shortly, but until then, the peace and grace of Christ be with you.
