“I once asked a little boy why the sea was salt, and the boy, whose father was away on a long journey, said right away, "The sea is salt because the sailors cry so much." "But why do the sailors cry so much?" I asked. "Because," he said, "they always have to go away from home- and that's why they're always drying their handkerchiefs up on the masthead!" And then I asked him, "But why do people cry when they're sad?" And he said, "That's because they have to wash the glasses of their eyes so they can see better.” ― August Strindberg, A Dream Play
