In its heyday, a very important pond.
I have been pencilling scale drawings of our garden on the graph paper at the back of my budget planner. The logic is that I will keep my budget planner for years, enabling me to settle a dispute in 2027 when we argue how much we spent on cider-making supplies in 2021.
It was amusing and instructive to go outside with a metal tape and measure all the necessary distances. For one thing, the area of the garden–which was thrown in with the price of the flat–is much bigger than the area of the flat. For another, our downstairs neighbour opened her door to ask what I was doing and had to be satisfied with my boring and obvious answer. I could have said I was figuring out how much fence we need, but I only thought of that later.
