Charles: (about Laura) She didn't have the slightest idea who you were, and as for the loan I wouldn't take it if it meant I'd lose everything. That little girl gave you something very important--friendship--and you took it and threw it right back in her face.
Mr. Sprague: I don't need any friends, Mr. Ingalls.
Charles: Well, that's a good thing, Mr. Sprague, because you don't have any! You know, I feel sorry for you. You can't give or take anything other than money, and as far as I'm concerned that means you don't have anything at all.
