Buffalo '66
Billy had a hard childhood so because of that, he become destructive towards himself and the people aroud him. Layla was only destructive towards herself and because of that she was with him.
„share your life, share your decision"
I also noticed that in the beggining Billy always orderded just a glass of water because he feel like that he does not deserve anything more. But later with Layla it changes to just a cup of coffee.
My favourite thing from this movie is the square flasbacks from Billy ' s childhood.
