Glad to see Stephen Leacock is still being read if this is the same Canadian humorist I remember reading so many years ago. He wrote an essay telling about he and his room-mate with their heads still under the covers because it was very cold, commiserating with each other because "they had not slept a wink all night!" Only to discover when they threw off the covers that the ceiling had fallen during the night, and neither had known it.
A couple weeks later, I woke up feeling the same way, and found that there had been a fire in the room below me, the firemen had chopped down doors and smashed windows, with sirens screaming, all without my knowing it.
