"I don't mind because I don't..." He trails off, struggling to find the concepts to explain, let alone the words. On one level, it is just so that he doesn't mind, and he doesn't really know why other people do. But on another level, he can make guesses, and know that the guesses are things that don't apply to him.

"I don't have any big secrets, and I don't have any - things that - " He gestures helplessly. "The way that people are sometimes, that they don't like it if people know something about them, even if it won't hurt them any other way, they just don't want anyone knowing? I don't do that."

The concept he is attempting to describe is something like shame, or embarrassment, or fear for one's reputation as a thing in itself. He can't quite bring the words to mind.
