I did the hitchhiking thing in my 20's. Up to Alaska and back. I know what he describes.
I wish everyone could have some experience like this. Because, like Kevin, I also have a positive view about strangers, about my fellow humans. And I have met a lot of people (friends, coworkers) where I recognize in them a fearfulness of the world. And I used to be like that too.
It really is a different and a wonderful world I think when you lose your fear of it.
Would you have a positive view about me, a homeless older man with schizoacffective disorder? Not looking for an answer, I just wan that in your head.
From what I have heard, women in their 20s have a materially higher probability of experiencing the opposite.
