A lot is said about who we are by the way we conduct ourselves; not what we say.
We "speak" through interpersonal methods every day. Agreeable dialog between business partners usually looks like both individuals displaying open posture and smiling at one other, signifying agreement and mutual respect. Commitment in a marriage can be reaffirmed by a sweet surprise, just because. A gesture such as this displays everlasting love and kindness. Even more obvious is embarrassment communicated through bright red cheeks and a clumsy verbal response.
