Soon enough you'll love this city even more, develop your street smarts and loose your bitterness. This city didn't kill your friend, some ******* did. Don't be ignorant yourself. Would it have killed you to tell the guy at 30th st "no thank you"? The person that shot your friend was able to pull the trigger because he dehumanized him. Is it any surprise you got called a mother****er by a homeless guy at the train station because you treated him like he wasn't a fellow human being by shrugging off his existance?
