Mr D, you should be proud on yourself for what you are doing brother, In America, there isnt anything like helping roomates who dont have their own car or rides. I know its tough for people like you but you will always be blessed. There was a time when I didnt have a car and have to wait hours to catch a bus to get to work or college. But my roomates they never said no , whom I respect more than my own brother helped me every single day and I would never be able to pay them back. Thank you friends for being like a family even at this place where money stacks up  with every hours spent.
