A branch of the post office that deals with letters that fail to reach their destination. Every so often, you'll get one of those human interest stories on the evening news that tell the rousing tale of a 120 year old letter that finally reached its destination after being sorted out by the Dead Letter Office. This raises the question, though...what exactly was the DLO doing with the letter for the last 119 years, and where were these letters hiding? And why do these stories only seem to show up on the news when it's conveniently a very slow news night?
