A lot of people don't understand or care why people are homeless, yes, sometimes its a choice, but why are they choosing to live in such a way that's the real question, nobody wants to live on the streets begging, but a lot of these people suffer from depression, low self-esteem, learning difficulties, misunderstood behavioural problems etc, they've given up, they don't feel like they have any value or place in society any more, you end up feeling numb, not caring any more, suddenly 'surviving' is just a way of life, you reach out for anything that will make you feel something again, drink, drugs, anything that will help you escape your mundane existence, next thing you know your addicted, lost, alone and homeless, it's not easy to crawl out of that hole, especially when people just think your scum.
