VACANT
Empty. Often descriptive of a house, flat, piece of land, mind,
etc. The vacancy of houses, flats and land is usually advertised on
big signs outside, and in newspapers. The vacancy of minds is
advertised by a lack of understanding of even basic things such as
gravity, a suitably vague sounding voice, and an annoying habit of
"oh yeah, I agree with you totally right.. but..."
