"It can't go on like this. I don't want to spend my life on the streets," George says, sitting on the plank bench where he spends most of his days. "As long as this little park stays clean, it's not a problem, but in the summer when people get drunk by noon, trouble can happen."

George walks into some nearby bushes, and returns to mix himself a rum and soft drink.

"I'm making here my private Carribean," he says, laughing and waving his bottle.

A visitor asks if George would be interested in using a "washing mobile." George replies that "washing isn't interesting." Then the visitor asks if George knows Frau Z., a resident known for calling the police to complain about the homeless.

"Do I know Frau Z.?" he repeats, snorting loudly and laughing.

"He'll be back this evening," says another homeless man.
