I noticed one scene where Ginger borrows a pen from someone to wright on a piece of cardboard. He wrote "NON-ALCOHOLIC, HOMELESS PLEASE HELP. This reminded me of when i see beggars they often have some kind of sign where they tell a story about them or a picture of their family members. Why I think these people have these kind of sign Is that maybe they don't know the language and can't say It for themselves. Or the don't wan't to disturb people by talking to them. A lot of the beggars that I see are probably refugees from some kind of conflict.
