Proverbs:

You have no fixed abode.
> Like the kingfisher, chattering while taking to wing.
The kingfisher, a restless, bullying bluebird, may be heard to chatter loudly when flying up from the ground or from a perch. The saying applies to one who suddenly spouts instructions to a group, then leaves, or to a leader at a meeting who impatiently interrupts a discussion with a burst of pronouncements, then ends the meeting.
> He's like the sea urchins between Ngiwal and Melekeok, on the ocean floor with its cover.
The sea urchin can be seen lying quietly on the lagoon floor, occasionally with a leaf like a hat covering its head. Applied to a man who acquires a wife or great wealth without working for it.
> A good leader, like rain, stills the ocean.
Rain falling during an ocean squall often seems to wipe away the winds and still the ocean. A good leader should be able to dispel the problems facing his people. He can calm down disputes and settle problems easily.
