I suppose this happens to everyone from time to time, but this is the first time it's happened to me: I just turned on the room light to find myself looking at an open box of paper.
Of course it *would* be a nearly *full* box of paper, too. So I said some words unbecoming of a gentleman, then had a diverting time developing blank sheets to find out how far the damage went, instead of the nice constructive printing session I'd been planning.
It turns out I only really lost a handful of sheets; after the first 5 or 6 they just have edge fog and are still usable. But still, what a pain in the neck.
