There was a man who sent his four sons to look at a pear tree in different seasons. The first son saw it in winter and said it was ugly. The second saw it in spring and said it was full of promise. The third saw it in summer and said it was beautiful. The last saw it in fall and said it was full of fruit. The man explained that they were all right because each only saw one season, and you cannot truly judge something by only one season of its life.
