After careful consideration, he put forward a request, "I understand that you’re thoughtful, but I don’t think this training can be completed very soon. You have to promise me that if your training takes a long time, you should at least teach them to read that poem first." Richard didn’t mind at all and it agreed quickly, "No problem, it really won’t take a long time. Language learning is not a linear process, but it’s something like an 'epiphany'—you might spend one year, two years, or even ten to twenty years teaching an ordinary parrot to speak, and it will still be dumb. But as long as it speaks the first word, the first sentence, it will naturally master the ability to speak. Think about that, don’t you humans learn language in the same way?" Zhang Zian thought about it, and found that what Richard said was actually true. Some infants could speak when they were less than one year old, while others didn’t learn to speak until they were almost two years old. The former children were not necessarily cleverer than the latter, whose 'epiphanies' just happened to arrive a little bit later. When babies learn to say "mommy", soon they are able to say other words like "daddy", "grandpa" and "grandma". Richard raised its wings and pointed to the birdcage. "They have learned to say ‘grey’, which means they have been enlightened. It probably won’t take long for them to grasp a lot of commonly used terms. By then, not only can they read the poem, but also they can help the elderly woman live a normal life. " Zhang Zian's thinking was stagnated for a few seconds before he realized what it meant by that. After returning from Guo Dongyue’s place, he told Richard what he had seen and heard in detail. He also mentioned that Aunt Bai was not very responsible for taking care of Guo’s mom. If Aunt Bai remained careless, Guo’s mom would be in danger sooner or later. Even though Guo Dongyue was not content with Aunt Bai, he could do nothing about it, for Guo’s mom only recognized Aunt Bai, and if Aunt Bai was replaced by another nanny, it’s hard to tell what Guo’s mom would do again out of suspicion and anxiety. When speaking his concerns about Richard’s training method, Zhang Zian was just telling Richard what he really thought, and he felt uncomfortable if he didn’t say it outloud. Who said that patients with Alzheimer's disease were not suffering with pain? He clearly felt the puzzlement and anguish from Guo’s mom’s face. Especially when she was looking at Guo Dongyue, it seemed as if every pore in her face was filled with despair, like she was sinking into a deep and dark abyss, desperately waving her hands, trying to grasp at anything. Though Zhang Zian spoke his mind inadvertently, Richard was listening carefully, and it thought of more aspects from these words. Richard was also faced with two ways: one was to simply teach the poem " Hymn of the Traveler " to the two red-headed lovebirds, and then its task had been fulfilled, and everyone was happy; the other way was to teach them how to really speak — not only could they justify for parrots’ speaking abilities, but they could also help the poor elderly woman and become her life assistant.
