Schroeder does very little talking in these early strips. Here Schulz puts the setup that would make more sense coming out of Schroeder's mouth in CB's, and doesn't even give him a reaction comment at the end. Although he is slowly approaching the other characters in size, it seems like he is still being purposely represented as pre-verbal, even though Lucy, who is apparently even younger, talks (and refers to herself in third person) frequently.
