In my experience personspeople living together in difficult circumstances (e.g. close friends, family members) often develop the abilitylearn to relate to the other person'seach other's non-verbal cues.
For instance; A spouse may go shopping with a list in hand prepared by his partner, and return with a few items not mentioned on the list - only to have his partner indicate one or more items were missed by oversight. Similarly roomies atpeople sharing a room in a hostel may merely by a glance communicate an unspoken understanding of intent & action.
Understandably such incidents probably do not occur with high frequency. They are, however, not totally rare either - which leads. This brings me to wonder whether such non-verbal communication may be taught rather than acquired?my question:
Can such non-verbal communication be taught rather than acquired?
