A homeless old man sits on the curb, looking up at you as you walk by. His clothes are ragged and dirty, and his face is weathered with time spent out in the elements. In a surprisingly cheerful voice, he calls out to you. "Hey, there friend! Got a couple spare change?" His tone is friendly and eager, despite his desperate situation. With no home or belongings, he has nothing left to lose, and he's happy to get whatever he can from anyone who walks by.
