I did a little traveling in my younger days and when in Geneva I stayed at a homeless shelter for several days as it was the cheapest option (homeless people did not have to pay but I did obviously) and I met some wonderful people there. Including an American who in a former life was a high flying lawyer, but when his marriage ended he lost everything and ended up homeless.
Everyone I met there was really friendly and had some great stories to tell.
About 20 years ago, there was a website with a staggering amount of excellent articles. Mostly about knives, but some flashlight ones. One of the best ones was an article titled "The Joy of Homelessness."
Obviously, sarcasm with the title. Written by an individual who had been homeless for numerous months at a time straight. Thankfully, his lot in life did improve. Detailed everything he went through. The good, the bad, the ugly, and the horrendous. Fascinating read. Unfortunately the site hosting the article became a zombie site for over 10 years. Tried logging onto it a couple of months back. But it's completely gone off the face of the internet. That article, along with many more interesting ones, gone! Maybe some other site is hosting the article. Worth reading if anyone stumbles onto it.
