perhaps

 Perhaps it is not even the person that our heart swells over, but what they represent to us. It is easier for us to become infatuated with one person who seems to embody everything that appeals to us than to obsess over separate things that aren't completely tangible/visible (states of mind, quirkiness, feminism, belief in alien life forms, the works).
 People are icons. We are simply walking, talking collages of everything that we have seen/heard/done/loved/hated. People are art(?).
