" Increasingly, life seems fractured, as if his past had been lived by someone else. It isn't just that the place he now resides in and the people around him are poles apart, it's like he himself is an entirely different person. The overriding obsessions and foibles of the man he'd once been now feel utterly ludicrous to the current resident of his mind and body. The only bridge is rage; when angered he can taste his old self. But in California, the way he is currently living his life, few things can vex him to that extent. But that's over there. "

― Irvine Welsh , The Blade Artist (Mark Renton, #4)
