i have known a lot of people over the years who have become homeless and met some people while they were homeless. I have had people sleep on my couch and I have taken in homeless children who's families fell on hard times. Entire families can become homeless real fast when one person loses their job for health reasone, job ends, or whatever reason. it is not always about alcohol and drug abuse. We also have a state with not enough resource for our mentally ill (NO ITS NOT THEIR FAULT THEY HAVE THIS CRUEL ILLNESS). Also a lot of our mentally ill leave their assisted living homes because several of them are very abusive! (Yes I do know this for fact and have witnessed this)
