We have the amazingly modern technological convenience called the drier.

Well, Jazz-O, here on the west coast of the US of A, there's an energy shortage, so the electricity-hungry clothes drier may well give way to something like the airing cupboard. Why waste heat that would otherwise go up the chimney? Oh, I know, NOT wasting resources is very un-American, so I may risk being thrown in jail or censured for thinking that the Brits have a good thing here. When I first saw the term, I thought It must be something to let one vent his grievences! Maybe we could use the term thusly on this board, i.e. "airing our dirty laundry."
