I once worked at a place where, in the common area, a table held a printer, a copier, a fax, and a shredder.
I thought: that's a nice portrait of the document lifecycle. Birth, reproduction, propagation, and death.
Then one day there was a big red-letter sign on the shredder: "THIS IS NOT THE FAX".
I was always curious who destroyed what, but maybe an explanation would spoil it.
