There once was an old man aged 50, who had a lazy son aged 30. The son
couldn't earn his own living, and still depended on his old father for food and
clothing.
The old man was very worried about him, so he took him to the fortune teller to
have his fortune told. The father and son both belie
the fortune teller's prediction that the father would live to 80 and the son to
62.
After having found out how long they were going to live the son was very sad.
His father comforted him.
"Don't be so sad! You are only 30 now, and still have 32 years of good days
ahead of you."
"I'm not worrying about my own age. It's just your age
which causes me great anxiety," the son said.
Upon hearing his words, the father was deeply moved, and in tears said,
"Don't worry about me so much I've got 30 years ahead of me too."
"I'm not worried about your age either," said the son, "I have
figured out that you'll die two years earlier than I. So whom will I depend on
in the two years after your death?"
