Even though they could have afforded to live anywhere they wanted, tradition dictated they stay on their tiny island home.
Eventually, their king became frustrated and called a meeting of the tribe's elders. He said he wanted them to figure out a way he could enjoy his wealth, and stay within traditional guidelines.
After much consideration, the elders suggested he build a magnificent throne. When he objected there was not enough room in his hut for a throne, the elders suggested he call in an engineer to solve the problem.
Soon, the king's tiny hut was rigged with an elaborate system of ropes and pulleys. He could lower the huge throne for use during the day, and at night, he could haul the throne up, and lower his bed. This was truly the best of both worlds for the king.
Unfortunately, after a few months of constant use, the ropes frayed, and one night, the throne slipped and came crashing down on the king, killing him.
The wise men of the island recognized a lesson in this experience and added to the lore of their people this statement: "People who live in grass houses should not stow thrones."
