"What do you mean by that?"
### "Since this problem is so difficult, you should at least give the kids a month, shouldn't you? You only gave them two weeks. Who could finish it?"
### Dewitt replied irritably, "I know they can't finish it. Since they can't, I'll explain it to them!"
### Deng Puhe said, "There was a farmer who grew rice. He squatted by the field, staring at the seedlings and hoping they would hurry up and grow. After watching for half a day without seeing them move, the farmer couldn't help pulling every seedling upward with all his strength. Satisfied, he went home to sleep."
### Deng Puhe said, "The next day, he saw that all the seedlings had died!"
### Deng Puhe said, "Dewitt, you're pulling up the seedlings right now! You're not letting them solve the problem themselves and are just giving them the answer. That won't lead to any real improvement!"
### Dewitt said, "What can I do? My health is getting worse by the day. I'm afraid I'll die before I've taught them everything they need to know. I'm anxious!"
### Deng Puhe froze, staring at his phone without moving for a long time.
### The office fell silent, with only the faint sound of water flowing through the radiator.
### He was suddenly overcome by sadness. He remembered how he and Dewitt had argued endlessly over problems, and how they had feasted in restaurants, pointing at undercooked dishes and cursing. In his memory, Dewitt had always been a vigorous old man.
### How had it suddenly become this way...? Why was his lively old friend thinking about dying every day?
### Deng Puhe said, "It's fine. Even if you kick the bucket, you'll still have me. I'll bring your students up!"
