Grandpa said, "Mr. Sun has been sick for many years and doesn't see anyone. I'm worried he won't be able to teach Xiao Man for very long!"
"If he can't teach, why would he take Xiao Man as his apprentice?"
Xiao Man quickly explained, "That's not it, Grandma. Mr. Sun didn't say he was taking me as his apprentice. He just said I have a lot of talent and was willing to 'lend' me this precious set of medical books to study. When his direct descendants return someday, I have to give them back!"
"But didn't you just say he was willing to teach you? If he's teaching you, how are you not his apprentice?"
"Well... teaching is one thing, but he never mentioned taking me as an apprentice."
Grandma frowned slightly. "What kind of arrangement is that?"
