Anything Built On Sand

It's so fragile, stately and tall... standing alone in the middle of the dry sand so brittle; a puff of wind can make it fall! The whiff of rain is carried by the vagrant clouds, build it, boy with quick hands; it's already sundown! It's the ingenuous creation of the smallest castle; what a perfect imitation... giving it an image too humble! Ah, know before hand anything built on sand will soon end up into the roaring sea: waves are cruel, they accept no plea!
