That was a rotten school
Carlisle was founded as a school but it was really a prison to "kill the Indian and save the man". You didn't say things like "I'm not sure I'm going to stay". You didn't make choices. They were made for you. Carlisle students didn't go on to college; they were trained for various manual labor jobs, servant work. At the same time they were being "civilized" to Anglo ways, they were taught they would always be second-class citizens. I don't know about the time Thorpe was there - that was later when it was more of a prep school, so maybe talking like that was allowed, maybe things were a little more free. But the stuff they show you about not speaking Indian and so forth were real. Children were beaten and worse. The lucky ones were taken away by their families, or ran away, or died. I have trouble believing that something like the traditional Indian songs, dances and dress at the vacation party would have been allowed even as an exhibition. As I said, maybe things had changed a bit by Thorpe's time. When the one guy says "These natives I'll never get used to them" and he's Indian himself, that's what they wanted you to do. You had to change all your thinking around. Look up Carlisle Indian School on line.
Let's just say that God doesn't believe in me.
