When you’re requesting information from someone, and he has information he doesn’t want to share with you, often what he’s saying to himself is, “I can tell them this, this, and this, but I can’t tell them all of that, because if I told them all of that, I would suffer consequences.” It’s the equivalent of him standing on the edge of a cliff—if he takes one more step, he’s a goner. So he says to himself, “I can only tell them up to here.”
