You ever think about what we do on a daily basis.  How much of it is informed by what we see presented as normal.  For instance,  on television,  hugs between men always end with a pat on the back.  The only time you see a full hug is when the man is breaking down,  when the scenario is that he is emotionally overwhelmed.  Is it that this is a case of TV portraying society or is it something else.  Speaking visually,  it is advantageous to have a way to signify emotional turmoil in a way other than crying.  So is it that the hug variations come from a need to show visually what is essentially internal,  or is it a reflection of society.  And if it is a reflection,  which is the original image.
