According to the tale, a famous ship captain was noted for keeping a small chest, always carefully locked, in which he kept a small, secret notebook. Each day he would carefully scrutinize the notebook, replace in the chest, and carefully lock it. The key never left his person.
Because the captain was so successful in every endeavor, many wondered about the contents of the secret notebook, but he declined all efforts to get him to share.
When he died, full of honors and at a ripe old age, his first mate was quick to grab the key and open the chest. With pounding heart he opened chest and notebook. There he read: "left is port, right is starboard."

That is all.
