Just a quick extra note to A Bad Man who pointed out my potential spelling mistake talking of the fungus-like growth in my shower as mould, when I should have said mold. It seems that I am in good company, with a lot of people on the web having the same problem, and some of them not even agreeing as to the correct spelling. I would say that, on balance, using the "mold" spelling would have made me most right as a British person, although I reckon at a push I could still consider myself belligerent and sarcastic (i.e. British) had I spelt it "mould".
I would have expected nothing less from the Bad Man but correctness, and I also wish him a speedy recovering from his hand job (he has been in hospital getting it fixed).
