There's a homeless guy in my city (one of many, unfortunately), who sells his own poetry in the form of little DIY anthologies, for small donations. He told me that he didn't want to beg without giving something in return. Kindness flows both ways; my small gesture of gratitude for some original artwork hopefully contributed towards a bed for the night, and was greatly rewarded with the realisation that the homeless are not and should not be voiceless.
