I particularly liked the one about 'temporary' school buildings. The school I taught at was built immediately after World War II, with a 'temporary' block being built first, while the main building was constructed parallel to it. That 'temporary' building became known as the 'Bristol Block' because it was put up by workers from the Bristol Aircraft company (who would have otherwise been out of work after the war, using aircraft components. So it was made of aluminium, glass, aircraft panels and (as we later found out) asbestos. It was built with a maximum two-year life span but it was still there when I joined the school in 1975. It was also still there when I left, 15 years later! (Fortunately someone had the good sense to set fire to my old classroom a year after that, burning the whole block to the ground!)
