Les mots vont, les mots viennent

A lonely man sits as he writes a love letter. The letter is an account of memorable moments during the early stages of what is now a long-distance relationship. It also hints of the delusional state in which the man is. When he finishes writing the letter, sealing it, and putting the envelope under the door, he waits for the reply that will eventually slide back under the door. The man picks up the envelope that carries the reply and begins to read it as a female voice-over reads the very same lines that he had written in his letter.
