In a field one summer's day a Grasshopper was hopping about, chirping and singing to its heart's content. An Ant passed by, working hard to carry an ear of corn to the nest.
"Why not come and chat with me," said the Grasshopper, "instead of working in that way?"
"I am helping to gather food for the winter," said the Ant, "and recommend you to do the same."
"Why bother about winter?" said the Grasshopper; we have got plenty of food at present." But the Ant went on its way and continued its hard work. When the winter came the Grasshopper had no food and found itself dying of hunger, while it saw the ants distributing every day corn and grain from the stores they had collected in the summer.
