Maybe

Once upon a time there was a Chinese farmer who lost a horse; it ran away.
 All his neighbours came around that evening and said, "That's too bad."
 And he said, "Maybe."
 The next day the horse came back and brought seven wild horses with it,
 and all the neighbours came around and said, "Isn't that great?"
 And he replied, "Maybe."
 The next day his son was attempting to tame one of the horses and was thrown from it and broke his leg, and all the neighbours came around and said, "Well, that's just too bad isn't it?"
 And the farmer said, "Maybe."
 The next day the conscription officers came around looking for people for the army,
 and they rejected his son because he had a broken leg.
 All the neighbours came around in the evening and said, "Isn't that wonderful?"
 And he said, "Maybe."
