I enjoyed my time in the United States. I stayed sixteen streets away from the Capitol Building in Washington, DC. While I was in the United States I visited the states of New York, Virginia, and more. I also visited Canada and I loved it there. 
     In the begining it was hard, but then I made friends. It was such a good experience that I cried when it was time for me to return to Mexico.

How do you say it in your personal own words? I can translate words, but I can think and speak as a native person :(.
