What’s the problem? I can see a small amount of debris in the water, but a little flotsam and jetsam in a pool surrounded by this amount of greenery is to be expected.

(Seriously: the pool is filled with rubbish, spied through the oily water. The original steps, metal and plastic affairs which hooked over the side of the pool, have long disappeared. Hence, I wouldn’t spend any time larking about here at night.)
