On Friday evening, the two lads who were working on the base disappeared, leaving the hose and extension lead still attached in the kitchen and stretching right across the patio doors. I managed to get the hose tidied up by taking one end and walking round the wet concrete to the window and then rolling it up. When it came to the extension lead, it wasn't quite long enough to walk round with it, so divergent thinking was called for.
Back in the kitchen, I unplugged it, then climbed out of the kitchen window, (one half of the window on the left of the picture) plug in hand, and walked round to the gates so that I could roll it up. Sounds complicated? Just a bit.
