An addiction to silk underwear does not necessarily imply that one’s feet are dirty.[Que le goût du linge fin ne suppose pas forcément qu’on ait les pieds sales.]
I admire addicts. In a world where everybody is waiting for some blind, random disaster or some sudden disease, the addict has the comfort of knowing what will most likely wait for him down the road. He’s taken some control over his ultimate fate, and his addiction keeps the cause of his death from being a total surprise.
