A river always likes to flow br downhill - from up to down - br its water somehow seems to know br to find the nearest town. br br The fishes aren't quite so smart, br they often swim uphill, br but this can be quite slow and hard, br though using tail and gill br makes up for lack of proper thinking br and also keeps the fish from sinking. br br Could you explain to me why it's so, br that rivers don't stay home? br Who did invent the constant flow br that makes the river roam? br br It's restlessness, you say my friend, br that it's like smoke that billows. br And why do all the rivers tend br to have their weeping willows? br br Because, my dear, the willows weep br their tears straight into streams. br They do have promises to keep br it isn't what it seems. br br I think that happy rivers must br have tears to keep from gloating. br They also tend to settle dust, br stirred up from too much boating. br br So, rivers flow with fishes in it, br and happy waves are normal. br But weeping willows, every minute br shed tears to keep things formal. br br When weeping willows finally die br and no more tears come down, br the rivers rise from low to high br and flooding comes to town. br br So each things has its usefulness. br Its role, which was designed br by higher powers who see this br as bag balm for the mind. br br And man has never learned to stay br away from interfering br with Nature's Laws and Nature's Ways, br that's why the disappearing br of trees and rivers, fish and man br is something that we should, br prevent by doing what we can: br And nothing would be good.
