An old man began to plant fruit trees on his land one day.
A young man came by and asked, “What are you doing?”
“Planting fruit trees,” the old man replied.
“But you won’t live to harvest and eat of their fruit,” the young man exclaimed.
But the old man answered, “The fruit that I have eaten and enjoyed in my lifetime has been from trees that were planted by people who lived before me. So I will show my gratitude of them and the trees they planted by planting these young trees for the people who come after me.”
