I feel you. When I moved to Cottage Grove, 20m south of Eugene about 7 years ago I befriended a homeless couple and gave them all sorts of stuff. It was only after learning from the girl that A. they wanted to be on the streets, and B. all the stuff Id given them was broken or torn and ripped up that I decided to not help the homeless anymore like that. I'll give' em food and whatnot, even some weed but that's where the buck stops.
