What causes an attraction to another person? One could say physical attraction. Which in all its glory is completely true. But what happens after that? And what happens to some of us who get "obsessed" if you will? Why do they become like a drug that you can't get enough of? In the same sense in some cases when you have satisfied that physical attraction and gotten over the "obsession" you are left wanting to get as far from the person as you can. Is it because you never really knew who they were and it was just an animal passion that once faded, you see the real person?
