After buying the flowers and vegetables, we were listening to Beethoven Lives Upstairs in the car. Everyone was saddened that Beethoven - being deaf - couldn't even enjoy his own music. Bobo got excited thinking that "in heaven he'll finally get to hear it!" To which Elbow promptly replied, "he might not even be in heaven, he did have quite a temper!" Big sister's response: "No, God will be extra gracious to Beethoven because he had special needs."
Not exactly sure if either argument can stand on it's own; but hey, combine the two girls and you've got the Law and the Gospel covered.
