Once, when I was tutoring Chinese to a 14 year old student, he asked me a question, which I had to think about.
First, he said, “Learning Chinese is difficult.”
I asked why he felt this way. He said, “Well, I can understand learning to speak, but all the reading and writing is done by memory, so it’s hard.” I nodded.
Then he asked me, “Really, when will I ever practically use Chinese to read or write in my life?”
This boy was the son of a doctor and a businessman. He focused on practical things, and he was very smart and driven.
I thought, yes, his question makes a lot of sense. He probably will not be writing letters in Chinese or reading Chinese books and papers unless he goes to live in China, falls in love with a Chinese girl or enters a field where he use his reading and writing.
Then the answer came to me, and I said, “It is good to learn another language because it teaches your brain to think and see differently.”
He thought about this, and we continued with our lesson.
