Bit of fluff

adhering (like that) to top of fire extinquisher, another thing taken down, it is very very old and probably doesn't work although somewhere in garage we have the refill. We are both kn¥¥¥¥¥¥¥¥d, having just moved all the boxes containing new kitchen from one side of conservatory to the other. The delightful Summer weather is not playing our tune, and rain is leaking in. We did take precautions against this but felt it was not enough and the boxes have in large letters "keep dry" so rather than have sleeplesss nights thought we'd have a jiggle around.
Now what can I do for rest of afternoon, tennis likely off, gardening definitely off, I can always clean this fluff off, we may have to put it back again...
