Oh, I was just so tired yesterday evening that I went to bed before eight and straight to sleep, with the result that just before three I was up and doing. Such a pain because I have friends round this evening and need to be awake. Fortunately, as it is Saturday, I can have a kip during the day, and will. Having said that, as I type, I can feel the sleep waves rolling in so will go with the flow and back to bed. Back later . . .
