"There is no pleasure to me without communication: there is not so much as a sprightly thought comes into my mind that it does not grieve me to have produced alone, and that I have no one to tell it to."
--Michel de Montaigne

"Communication is message assimilation—the respondent must be shown to behave in some way that proves they [sic] have come to accept the message, not merely to have received it."
--Mark Crispin Miller
