Our flat is the same - I enjoy letting the mould grow on the wall, in its pretty, grey shapes. And every Summer, as the world turns in its natural course, there's the seasonal infestation of fruit flies around the bin. Nature's lovely. Maybe our romantic adoration could be rediscovered if we admitted more things as being 'natural'? People, too, provide a kind of undergrowth, and their greater structures form some very fetching accretions.
