For my own part, I am pleased enough with surfaces.
In fact, they alone seem to be of much importance.
Such things for example as the grasp of a child's hand in your own,
the flavor of an apple,
the embrace of a friend or lover,
the feel of music, the bark of a tree,
the abrasion of granite and sand,
the plunge of clear water into a pool,
the face of the wind,
what else is there,
what else do we need?
