Exactly I also have some that I help out from time to time with a bit here and there, I remember one when I lived in queens a similar story to this guy who slept in the subway, about once a week would see him and pick up a pizza and sit with him and share the pizza and talk, in the end this is one of my favorite personal moments, one day he had been to a meeting with social services or something so was cleaned up when I saw him so I took him to the local pizza place and we grabbed pizza and ate there, the owner of the Little pizza place came and sat with us and they got chatting, I had to leave but was pleasantly surprised when I walked past the pizza place and the guy was working there when I eft the area I swapped emails with him and we still keep in touch and his life has turned around :)
