It was mostly just Lu Li answering the old man's questions.
The old man was quite capable at speaking and alleviated Lu Li's feelings of being interrogated. He didn't ask about whether Lu Li had a car, a house or how much money he had. Instead, most of the conversation was just about trifling matters. He heard that Lu Li was recently beginning to listen in for some classes in the university, so they also talked about this.
As for the question when Lu Li would marry his granddaughter, that was more of a joke.
His granddaughter would not be that easily married away.
Lu Li talked about some of the things that he learnt from sitting in some of the classes, as well as the things that he couldn't quite understand. What surprised him was the old man's intelligence and understanding of different areas. He was able to give clear answers to Lu Li's questions and also made it easier for Lu Li to understand as well.
