He was one of those people whose ideas are too lively to be confined
in their brains and spill out into the world to the consternation of
passers-by. He talked to himself and the expression on his face
changed constantly. Within the space of a single moment he looked
surprized, insulted, resolute, and angry--emotions which were
presumably the consequences of the energetic conversation he was
holding with the ideal people inside his head.
