I'm so wide awake at 3 in the morning and so clear-headed, you'd think I could solve the problems of the world. Instead, this morning, I started fussing about my robe, the one I received when I was awarded an honorary doctorate. I was measured for it wearing the last (as it turned out) pair of high heels I owned., and it was a litle long when I wore it officially but I have since turfed the shoes and shrunk a little so it is definitely too long now. So there I was at 3 a.m., wondering, if I should ever need to wear it again, whether I should buy new shoes or have it shortened. Oh dear.This is not productive.
