Now I have a lot of tedious work because it needs everyday a same operations but I hope better a future. My likest films is Onegin, Vampire Chronicles, Eyes wide shut, Star Wars, Matrix etc. More I like sing karaoke, sometimes to play computer games. Good games is not make often. Last years most of all I like hear music. My favourite musicians are Laura Pausini, Nickelback and other somebody little by little. I want to learn paint I even bought colours. And almost free time spend for English :)
