Carl is a Vietnam Vet who hangs out in Washington Square.  After I took his picture I handed him a couple bucks so he could get some water as the temperature was 95 degrees and climbing.  He was grateful and thanked me profusely.  Right after I handed him the money a buddy of his came by and said, “I wish I had a buck.”  Carl did not hesitate for even a moment before handing over the money I had just given him.
