During my time living that life, and certainly in the years afterward; I've always found it weird how some addicts seem to gravitate to crime to feed their addiction almost immediately, while others take a slow trajectory towards burglary, robbery, etc. And then some, never go that route at all...
Its weird how that works....
My inclination would be to say that the violence Walker saw may have been a factor.
For me personally, my drug issues never approached that level because I was always- statistically - rich.
Not to make light of the issue, but as David Lee Roth once said “It’s not a drug problem if you can afford it”.
Have you read the book, Tyler? If not, I think you’d really enjoy it.
