An indian story "five loaves of bread"

Once there was a man who went to the market every day. He always went there at the same time and he always bought five loaves of bread.
One of his friends often saw him when he was on his way home with his five loaves of bread.
One day he stopped the man and said, "I meet you every day, and I always see you with five loaves of bread. Why do you always buy five loaves, not more or less?"
"I lend two and with the other two I pay my debt."
"I don't understand you", said the friend.
"Then listen: my wife and I eat one loaf, I give two loaves to my children, and two loaves to my father and mother," said the man.
