I became homeless when I was 18. On my first day on the streets I was sitting at a bus stop crying and a homeless guy came up and asked what was wrong. I explained my situation and told him I didn't even have enough money for a bus ride. Without hesitating he pulled out a baggie of coins, counted out enough for his own bus fare, them gave me the rest. That act of generosity will stick with me for the rest of my life.
