I had a similar, but much more extreme, example of this occur at work a few years back. We sent paper invites to an event. Time went by, we went to a paperless system, and the day of the paper invite had come and gone. It got to the point where we didn't think about those invites (it was for an annual event) very often....until one came back, marked, "Return to sender."

Four years later.
