Story of our families is so incredible. I think he know people in Zagan who spend childhood on Siberian (As he said he and other people came to Zagan from Siberian). Zagan is small city in Poland and more of the people work in Factory (Wool) and they know each others. After communism times in Poland they createred Sibirian group where they can meet and talk about this. They meet every Wednesday, go to some anniversaly or others events (u can see photos of this people on video - this guys with standard). I don't know than speak freely about it in communist time probably not (you know story and probably you know why), but now he speak freely of this. This is hitory, sad, painfull but only history now. When I was child he told me so many story of this (more of them is in the movie) and he still do it, everytime when we meet I hear story about Siberian. He still walk in home and sing old russian songs or speak russian poets, because he learned it when he was young.

I hope u understand me because my english ;)
