Laura: I'm sorry, Pa.
Charles: For what, Half-Pint?
Laura: For thinking you didn't care about Jack when he almost drowned.
Charles: Didn't care? I blame myself for not putting him in the wagon. I should have taken into consideration how tired he was. I was just so full of guilt for letting him drown.
Laura: But you only said you were sad about not having a good watch dog anymore.
Charles: I guess I just couldn't find the words to say what was in my heart.
