Through nonverbal communication, observation, we can tell quite a bit about one another from a comfortable and safe distance. That permits us to avoid some folk that we don’t think we would care to know and allows us to approach others that seem to be appealing to us. The problem with nonverbal communication is that it is ambiguous and we don’t really know how much they weigh, how tall they really are or that they really have an education. We can only apply what we have learned through experience over the years. Unfortunately it is still ambiguous.
