Nope.  Fraid not.  We're not selling something and we're not overly optimistic either.
We've all been brought up to assume that there's not much any of us can do to make a difference.
We're also all brought up to look at homeless people as beneath us.  To assume that it's their fault
they're homeless.  Neither of these things are true, and we, as a group, are merely trying to prove this.
