I've remembered my travels abroad. I visited South Africa last year, and I enjoyed the African arts and music. Two years ago, I went to New York. I visited many places like the Liberty Statue and the Rockfeller Center. I travelled to Argentina in 2003, when I was sixteen. I danced the tango and played soccer with "hermanos" in Buenos Aires. I've thought about my travels and I've seen that I've never been in Asia. Now, I'm planning travel to Tokyo next year, I want to enjoy the Japanese culture.
