In any relationship that comes to an end there's never just a baseline reason why. You say 'Oh I broke up with my girlfriend.' Someone says 'Why?' You say 'Well you got three hours? And then maybe after I tell you my version you've got to talk to her.'

I was always raised on cowboy films and then when I could start making choices about the movies I wanted to watch I found myself wanting to watch gangster films which were slightly more sophisticated than the baseline stuff that was in westerns.
