We're bums but we all provide for ourselves, we know how to survive in the urban jungle. We know how to tell jokes, play songs, spare swipes on the subway so you can get where you're going without having to pay. You know there's always a way. It's about not having your priorities so high you're not able to survive without a job.
Even homeless people are welcome. There's a difference between a homeless person and a traveler. A home bum is someone that wanders around the city and begs for change all day, doesn't want to get a job, doesn't want to get any help, doesn't want to rent an apartment, lives in a box, is an alcoholic, a junkie or whatever. These kids, a lot of us don't work, play music or solicit for money, tell jokes or turn tricks. Anything goes these days as long as it's not hurting someone intentionally.
