Did You Know?
The riddle cleverly uses "letter" to mean both an alphabet character and a piece of mail! Envelopes have been used for centuries, with the first mass-produced envelopes appearing in 1820s England. Before envelopes became common, people would fold and seal letters with wax, creating their own protective covering. Today, over 100 billion envelopes are used annually in the United States alone!
