Living like this let's me be more of an observer of the world than to be a part of it. You kind of float in a strange reality at the edges of society. This is made 'worse' by the random normal people you see everyday. Most of them don't want to see you and will do anything not to acknowledge that you exist. For example, when your flying a sign at a grocery store curb and the driver almost has a car accident bc they refuse to look at you or even in your direction. That happened twice today. If they look, they might have to acknowledge you, if they acknowledge you they might have to question themselves.
The things they see as problems, the things I used to see as problems, I could care less about. By the same token, the things I see as problems, they completely take for granted. I'm not worried about getting a whopping three percent raise at work, I'm worried about getting enough day labor to feed my ass and get me out of town.
I once thought that as soon as I got tired of traveling that I could just quit and live a normal life. I look back at that now and I can't believe what a complete dumbass I was. Even if I could stand to be in one place and have a house I wouldn't be 'normal' bc I just can't see myself ever caring about the bullshit that normals care about ever again. The things that I've learned, the things I've done on the road have fundamentally changed me forever. Terms like good and bad are relative so I won't judge the changes, it's probably enough just to admit to the change.
I suppose this doesn't deal with old friends and family but I think it may help to explain the disconnect some may be feeling.
