good sons

Three sons left home, went out on their own and prospered. Getting back together, they discussed the gifts they were able to give their elderly mother:
The first said, "I built a big house for our mother."
The second said, "I sent her a camel with a driver."
The third smiled and said, "I've got you both beat. You remember how Mom enjoyed reading the Divan-e Hafez? And you know she can't see very well. So I sent her a remarkable parrot that recites the entire Divan. It took elders of the town 19 years to teach him. He's one of a kind. Mama just has to name the Ghazal number, and the parrot recites it."
Soon thereafter, mom sent out her letters of thanks: "Ali," she wrote one son, "The house you built is so huge. I live in only one room, but I have to clean the whole house. "Reza," she wrote to another, "I am too old to travel. I stay most of the time at home, so I rarely use the camel. And the driver is so rude!" "My Dearest Nasruddin," she wrote to her third son, "You have the good sense to know what your mother likes. The chicken was delicious."
