Once upon a time there lived a man named Önyö-makö. He had five daughters-in-law: one made of clay, another of birch bark, another of hay, another who was a broom, another a bubble. Önyö-makö himself just stood around. The daughter-in-law of clay he sent to fetch water. It began to rain and she was washed away. The daughter-in-law of birch bark he sent to light the fire in the bath. She struck a match, her tail caught fire, and she burned up. The daughter-in-law of hay he sent to feed hay to the cow. The wind began to blow and swept her into the mouth of the cow. The cow ate her up. The daughter-in-law who was a broom he sent to sweep the shed but she got caught between the floorboards. The daughter-in-law who was a bubble laughed and laughed until she burst. And Önyö-makö just stood around.
Would anybody care to tell the class what the moral of this story is ?
