““Love has been many things throughout history: the simple comfort of the familiar, having a person to know and being known by that person in return; a connection born of shared experiences, an irrational joy in another's presence; a particular calming influence that one member of the couple may exert on the other, or that they both provide to one another. A combination of all these and myriad other things can go into making one person wish to stay tied to another. Anyone who is not in the couple--that is, everyone else in the world--will not understand precisely how or why it works for two people.””
