In a relationship when things are really great you don't need to say anything and just enjoy the other person. Sometimes with a couple it gets dark and you don't know what to say and that silence can last all day. Other times you don't want to stop talking because you don't want to lose one another.
It is also rarer to find happiness in a man surrounded by the miracles of technology than among people living in the desert of the jungle and who by the standards set by our society would be considered destitute and out of touch.
