It's not good, is it? I just looked under a pile of papers on my desk and found a little tower of greeny blue dust which I can now see used to be an orange. I've had to move desk for the day because even though I've put on rubber gloves, removed it and Dettoled my desk, it mouldy musk is lingering.
I want some more good mould stories. (I once found a pizza under my bed that had bene there for about a year but then I am a total midden).
