90% of our communication is non-verbal

Sometimes language can't even read the music of meaning.

Physical expression and attitude have no age, language, or species barrier."

When I say or write something, there are actually a whole lot of different things I am communicating. The propositional content (i.e., the verbal information I'm trying to convey) is only one part of it. Another part is stuff about me, the communicator. Everyone knows this. It's a function of the fact there are so many different well-formed ways to say the same basic thing, from e.g. "I was attacked by a bear!" to "Goddamn bear tried to kill me!" to "That ursine juggernaut did essay to sup upon my person!" and so on.

Few realize how loud their expressions really are. Be kind with what you wordlessly say.

What said those two souls communicating through the language of the eyes, more perfect than that of the lips, the language given to the soul in order that sound may not mar the ecstasy of feeling? In such moments, when the thoughts of two happy beings penetrate into each other’s souls through the eyes, the spoken word is halting, rude, and weak—it is as the harsh, slow roar of the thunder compared with the rapidity of the dazzling lightning flash, expressing feelings already recognized, ideas already understood, and if words are made use of it is only because the heart’s desire, dominating all the being and flooding it with happiness, wills that the whole human organism with all its physical and psychical powers give expression to the song of joy that rolls through the soul. To the questioning glance of love, as it flashes out and then conceals itself, speech has no reply; the smile, the kiss, the sigh answer.
