Anybody home?

Yet more evidence of the innate stupidity of the world:

The management of the building I live in came up with the bright idea of printing a one page flyer exhorting residents to be especially security conscious in these summer months when building occupancy is low and incidence of break-ins is known to be high. They then slipped these little missives under each residents doorstep, with the result that all you have to do now to figure out which residents are away is to walk down the corridor and look for the telltale sign of a white sheet peeking out from under the door.

Smart, huh?
