If you are homeless, what does it mean not to have a post box where people can contact you; what does it mean not knowing where you're going to sleep at the end of the day; what does it mean not having a place where you can store what little you might possess. So dealing with homelessness in itself is a huge thing for most people who are commentators [on] or benefactors to poverty.
