Arthur

Likes marbles, identifies with marbles, finds them sensorially pleasing (colors, textures, and sounds), intuitively breaks them down into concepts, becomes curious about their origins and looks up how they are made, owns a few he considers to be special, an appreciator - not a collector

Lou

Completely indifferent to marbles, sees no value in them, would not keep one (except Arthur, who is marble in nature)

Morf

Believes marblemaking is an artform that is beneath him, has not considered the conceptual aspect of marbles because he relies on artists to package information for him, could be tricked into appreciating marbles if they were referred to by a more aesthetically affluent term (for example: spheres)
