We are designed, by default (it is our root nature) to communicate, to connect in any given moment by sensing the energy, resonance, the tone and body language of other life forms and from that experience, of how we will respond.
This is largely autonomic in nature of course, woven into the fundamental fabric of being a human being. It is designed to connect us heart to heart, soul to soul, where we always want to be-long, our mobile phones, texts and emails will not do it, no matter how hard we try.
