i must admit i've had good stories...
i just took a sticker off my windshield the day before.. this bum insisted on scraping every bit of it off for me. So when i went to go get my cigs in the gas station as he was washing my window, i picked him up a pack of smokes and a coke. he was so happy... and said that he wished more people did that for him instead of just ignoring him and leaving him to "fight da streets on mah own"... if i member correctly his name was tom.
