Homeless Help

I have decided to give my left-over summer train passes to the homeless people I could find hovering around the subway in chicago, in order to honor the bum that helped me out (a little ironic dont you think) once. A few months back, I was in a hurry trying to get into the T (boston subway), and I didnt have enough money for the token, so a homeless guy let me in (in exchange to having me listen to his advice about how to do well in classes) I should add that his advice was well-received, I just wonder why he didnt employ it himself. If he EVER reads this, I hope he appreciates my good deed.
