[Boone catches that Niko isn't telling him something, but he won't press him for it. It's none of his business how Niko's friend copes with things.

[He wishes he was better at knowing how to cheer people up like that. He never has the right words, but if he could be funny sometimes maybe he would be. He's no good at that either, though. The best he can do is dry sarcasm that's very rarely intended to be amusing in the first place.]
