A Story is (a) Grammar; Narrative is Language. 

The infant's laugh is sound, her mother's cry as it leaves her room an utterance. "I" the instant the synapses connect to see the self, "U" as the front of the brain reaches to the back and we see the other.

The consonant gives shape to the vowel, form in the void of waves and particles. Shape and then figure, entity to character. 

A story is a sentence,  a relation to things in time connected by action or agreement or repulsion. A verb.
