My (nick)name "Polkan" came originally from a half forgotten folklore. Not everyone familiar with the tale itself, but I did read it.

Today Polkan is a name frequently given to a big chained dog, whos propose in the life is to guard and defend the house and all what is inside. He has an angry look and gets only bones to it.
Why did I choose this name? It's a sad story. Back in summer 1991 when I was a school boy I wanted to make a money for myself and with my two older friends took a job in a village close to our town. The third day ended with fist battle my friends did with the local youth. And me ended in the police (then milicia) station. I was detained for 3 days (actually only 1.5: evening, night, whole day, night until 5:00 am). There was a big picture of dog on my t-shirt, so they called me Polkan. I think it was a joke.
When I got home my elder brother gave me strong slaps. But at list he did not said to my parents were I was. It was him who talked with the cops (musora), saying he is my father.
Thet is all
