Epictetus picked a fur coat with rare lynx on one side and lamb on the other. He wore the coat with the lamb showing. That way he could appear common. For advantage hide things you don’t want known.
A Lynx was bragging to a Mole about how gifted he was by comparison. Mole heard a noise and sunk into the earth while a hunter killed the Lynx. Ooops! Pay attention at all times.
