It was only a matter of time before this happened, but that it happened at this time was due to yours truly wanting to photograph the Christmas baubles she had hung in the window, without the slats of the blind in the background. So I pulled on the string to hoist the blinds up, and they came crashing down in a shower of cement dust:
I had decorations in the window and expected them to have been smashed, but the only things damaged were the metal candle-holder/cookie tin, and this slat on the other blind:
This happened on Saturday. On Sunday the cavalry arrived, in the form of my father, who re-hung the blinds and glued the slat together and now I just hope the thing will stay up.
