"Not bringing lunch today?"
Walking with Qiao Yu directly into the community, the good guy asked in surprise, as he had planned to treat Qiao Yu and his mother to a meal today.
"From today, my mom will personally cook for me," Qiao Yu replied.
"Uh, that's... pretty good," Lan Jie responded.
Qiao Yu turned to look at Lan Jie and said seriously, "If my mom is serious about something, she can do it well. But you're right; she does have some health issues, which is why she can't adapt to society, but she's normal."
Lan Jie wanted to point out that this sentence was awkward; being normal shouldn't equal having health issues and not being able to adapt to society, but seeing Qiao Yu's serious expression, he chose to keep quiet.
Even as a teacher, dealing with a very smart kid can be stressful.

"Oh, Teacher Lan is here again, come on in. Have you eaten?"
