Curious what a homeless person would do with $100, they gave him the money and 

then followed him to see what would happen. At first, his motives were misjudged and

 then what he did shocked and humbled everyone. The saying couldn’t be more true, 

"Never judge a book by its cover.” What a beautiful moment of giving caught on tape.
