He could learn to say any word except one. He could not say the name of his native town, Cotano. The man did everything he could to teach the parrot to say “Cotono” but he never succeeded. At first he was very gentle with the bird, but gradually he lost his temper, “You stupid bird! Why can’t you learn to say that One word! Say ‘Cotano’ or I’ll kill you!” But the parrot would not say it. Many times , the man screamed (大声叫), “Say ‘Cotano’ or I’ll kill you!” But the bird would never repeat the name.
