Czarny Roman (Black Roman), a homeless guy from my town, who used to wander the streets in a dark suit and hat (in winter he switched to neon-coloured ski robes). The story goes he used to run a black-market currency exchange in the 80s and was terribly rich, but either a business partner fucked him over or he lost it all at a casino; he went nuts and ended up on the street. A different story says he ran a coffee shop with his ex-wife. Some claim he used to study at the University here or even the Fine Arts Academy. He had a family (they were interviewed at his funeral by the press) who reside in New York and probably only they know the real story. He was strongly against drugs, cigarettes and alcohol; aparently used to discourage kids from smoking. He wilfully gave up social housing and spent many years wandering about and talking to people about art, poetry, music, yoga and death. He claimed he was immortal and once left a note on a napkin which gave a glimpse of his early life. Apparently he was born in 1950 and his mother was murdered by his father. He claimed Warsaw will be hit a with a meteorite and claimed to know the dates of death of passerby's. He never begged for help, even had his own food and was sometimes supported by people he talked to. I've never talked to him myself but he was on a "good morning" basis with lots of people here and seemed to be able to remember them well.
