Another time Mullah Nasruddin said to his friend, "In forty years of marriage my wife and I have never had an argument."
"I don't believe you" his friend said. "It is not possible."
"It's true", Nasruddin said, "We have not argued in forty years."
"Well how did you manage that?" his fried asked.
"On the day we were married we made an agreement that she would make all the little decisions and I would make all the big decisions."
"You kept an agreement for forty years!?", his friend asked.
"Yes", Nasruddin said. "And so far we've never had to make a big decision."
