Developing My Character

My character is going to be this one hobo.

Ive talked to him about five times. Its always the same thing. "Excuse me, Do you have some spare change? I'm trying to catch a bus to Santa Monica." Even if I had money I wouldn't give it to him. He doesn't realize I live right by the bar where he drinks all the time. Anyway from what I see this guy is just a regular drunken hobo. It seems like the only goal he really has is to gather up enough change during the day, so that at night he can drink his sorrows away. He has a lying sneaky side. Obviously since he lies to people with his "Santa Monica" story. He is a determined hobo though. He seems to get his drinks so how can he not be determined? This hobo is polite though. He approaches me kindly and leaves kindly. Hes about 5'9 or 5'10. Hes kind of balding on the top of his head but the rest of his hair is shoulder length long. Its pretty dirty and knotted up. He has this scruffy beard and wears the same red shirt with tons of holes. His old school nikes all tore up and dirty. He wears these horribly dirty, greasy, stained pair of jeans. What is surprising is that he doesn't really even smell. I dont smell cigarettes, alcohol, or any nasty smell. Just dirt. Deep down he must be very depressed to give his life away to hustling beer. Therefore this hobo is quite mysterious too. His past is hidden beneath is excessive drinking.
