WIP progress report: I have been sitting still for so long now that I have a sore knee - argh! And because of that, and because I'm so near the end and tying things up, I hardly slept a wink last night. Other consequences are: a filthy house, an absolutely messy garden, my social life in utter abeyance and my awareness of the cultural events around me - theatre, film etc - at a minimum.
I do NOT recommend this working method, but I just can't help it myself: if I try to stop, I just sit there thinking about it but not doing it, and unable to put my mind to a single other thing, apart from Killer Soduko (numbers are such a great relief from words!).
