The Rivers and the Sea
Once upon a time the rivers combined against the sea and, going in a body, accused her, saying; "Why is it that when we rivers pour our waters into you so fresh and sweet, you straightway render them salty and unpalatable?" The sea, observing the temper in which they came, merely answered; "If you do not wish to become salty, please to keep away from me altogether."
Those who are most benefited are often the first to complain.
