Once upon a time there was a grasshopper and some ants.  The grasshopper was singing and the ants were working really hard.  Then the grasshopper said "why are you working so hard in the hot, hot sun?"  The ants said " we are working hard because we are getting food for the winter."  The grasshopper said "I will do it tomorrow"  Then it was winter and the grasshopper had nothing to eat.

Work hard now because soon it will be too late.
