First of all, I have to say this is hilarious!
Second, teachers like that really hack me off. What she's saying is "He needs to learn to be someone different than he is." It reminds me of the art teacher (in a free-play setting) who pressured me to stop doing pencil drawing and do stuff with color. (Ironically, she also harped on how we should follow our own creative ideas and not someone else's.) And the camp counselors who would forbid me to read a book because I was supposed to be participating in group activities. And peers who would tell me that I think too much and needed to be more fun. Several decades later, I'm here to say that no one's attempts to make me more "normal" had the slightest effect. The key for me to be happy was to find other huge nerds who like to think too much.
I think your kid sounds fine.
