"No need."
"Let's go together to the school gate. I won't go out," Tian Yanzhen insisted.
"Then let's take the East Gate," Zhang Shuwen said.
"Not going for a stroll by the lakeside? It'll get lively after school starts next week."
"No, maybe another time."
"Alright!"
After a few silent steps, Tian Yanzhen suddenly sighed, "Mr. Hamilton passed away last year."
Zhang Shuwen was silent for a moment, then said, "Yes, a respectable old man. In your heart, you're probably complaining why it wasn't Simon Donaldson instead."
Tian Yanzhen laughed, saying, "I'm not that harsh yet. At our age, many things have become clearer. But speaking of which, Donaldson is 69 this year, right?"
Zhang Shuwen nodded, "Yes, I remember he's a year older than you."
With just a few words, the conversation touched upon the past history of the mathematics world.
