I have a customer who gets me to WFP her house every fourth Tuesday, [most recently was yesterday], and when I was down that street again today ,she was out cleaning the downstairs windows !!
She's a lovely lady, they are a nice couple in fact, but she has a mental problem, all her waking hours are spent cleaning, and she sometimes cleans the front door glass three or four times a day, according to her neighbour.
She can't manage the first floor, so I get paid for the whole house, and she does the bottoms daily - takes all sorts, don't it?
