Patterns.

What amazes me most about crystal stories is that they all follow the same pattern. Your hear about someone's changed behavior and you know how that story will evolve and end.

I sold crystal so that I could have as much as I wanted for myself to shoot up and not have to pay for it. I didn't even really consider myself a drug dealer, rather, I was simply providing a service for my friends. Isn't it amazing how we try to tart up even the most low-down and tawdry behavior so that we don't feel as shitty about ourselves as we really should?"
