I keep going. I know what I've done, the effort I've put into my life, my job. No one told me it was going to be easy, I didn't expect it to be, and it hasn't been. But I do what I have to do to take care of myself and my family. It all comes down to self-respect. I'm all for shelters as temporary lodging for those who, really and truly, have been dealt a terrible hand.
But I tend to believe more of them than not are just coasters, like Graig outlined up there. Especially the ones who are walking up and down between cars. I remember one guy who staked out a place on an exit ramp with a sign that proclaimed he was hitchhiking home to get to his kids, who needed him. He was there for 8 months, with a folding chair, a cooler and a little umbrella staked into the dirt. What a gig, huh?
We all look out for #1. Some of us have different ways of doing it.
