The builder came. He is what I would describe as a typical 'wog' (and I mean that in the nicest possible way). Shaved head, athletic build, tight designer shirt and jeans, nicely perfumed, and wearing lots of heavy gold jewellery. He prized off the skirting board and I was amazed to see the assortment of fungi growing on the wood. My damp problems is a mycologist's dream. "Definitely a damp problem", said the builder. He cleaned out the mess and said he's going to get back to me in a couple of days.
