“I spent last year in London. I’m from a small town, and London is a very big city. (...) There were so many people to talk to, but I always felt embarrassed about my English. I missed my family and my two cats. My roommate was always listening to loud music, so I rarely had the chance for a nice long talk with my parents. It was a good experience, but I am glad to be home!” Carla Fonseca – Resende (Neil J. Anderson, editado)
