Words?

When you speak, your words are in my head.
Not a stream of random consonants and vowels.
Not a hierarchy of nouns and verbs.
Not a set of sentences, nor a block of text.

That my ears hear the sound is of small significance;
For me to understand you, I must speak in unison
 - for a moment, despite all else, we think alike -

              Your words, inside my head.
