One day at the end of class, the teacher asks the class to go home and think of a story to be concluded with the moral of that story. The following day the teacher asks for the first volunteer to tell their story.
Little Suzy raises her hand. "My dad owns a farm and every Sunday we load the chicken eggs on the truck and drive into town to sell them at the market. Well, one Sunday we hit a big bump and all the eggs flew out of the basket and onto the road." When the teacher asked for the moral of the story, Suzy replied, "Don't keep all your eggs in one basket."
Little Lucy went next. "My dad owns a farm too. Every weekend we take the chicken eggs and put them in the incubator. Last weekend only eight of the 12 eggs hatched."; Again, the teacher asked for the moral of the story. Lucy replied, "Don't count your chickens before they hatch."
