I live in the same building as my parents, but we are in differents flats. 

I studied Social Education but I'm unemployed right now. I hope to start working next week as a  Children's Activities Monitor. I worked at an urban camp this past summer, and it was a good experience.
I'm a fan of pop music, and when I have the chance I enjoy going to concerts with my friends. I like sports, too. I go to a gym, and when the weather is good I go roller skating or hiking. In winter I prefer skiing. I love animals, and I have a dog named "Lya." I often take her to the beach because she enjoys running and jumping on the sand.
