This article tells a story about a man who had four sons and wanted to teach them not to judge things too quickly. He sent each of them to look at a pear tree at different times of the year. The first son saw it in winter and thought it was ugly, the second in spring and saw green buds and promise, the third in summer with blossoms and sweet fragrance, and the youngest in the fall with ripe fruit and fulfillment. The man explained that they were all right because they had seen only one season, emphasizing that you can't judge a tree or a person by one season. The message is to persevere through difficult times, as better ones will come.
