What drive's a man to be homeless?

[purplehaze]

The other day my girlfriend and I went out to eat. We live in the middle of no were and when i got off the interstate i noticed a man walkin and turned around to see if i could help him. Well when i got closer i noticed he looked scraggly, and i pulled up to him and asked if he needed to use my cell phone. He said no, i said is there not anybody that you could call to come and get you, he answered no but if i had any water that would be nice. I had just bought a 20oz drink and gave that to him because i was almost home anyway. But we live in the woods pretty much and theres not a store for about 3 hrs if your walking. He told me he lived in a city around my house but mispronouced it so i knew he was lying, anyway he was homeless and i was thinking on my drive home what could possibly happen in your life that you would be homeless. I thought about going back and getting him and smokin with him just so i could find out what drives someone to completely give up and not want anything in life, i've been pretty bad off before but never homeless. The reason im asking drugs forum is because most people would say its because of drugs but i dont believe that. If he's homeless he doesnt have anything, no money no food damn sure not enough money to buy a hard drug and i just cant figure it out. I just want some general input on what swiy thinks, If anybody has ever been homeless please explain.
