Surviving the Streets (#2)

Always, ALWAYS acknowledge people you know, even if you've only met them once. A smile, a nod, a tip of the hat goes a long way. What goes around, comes around. 'Cos loneliness is worse than hunger, worse than sadness, worse than anything dreamt of in your philosophy. And you might have friends now, but when you're all alone and one step away from the edge, an unexpected smile could save your life.
