I am so excited to right to you! I am a ten year old girl from Alexander Elementary in Katy,Texas. I love doing interesting sports, but I would say that my 2 favorite sports, are soccer and swimming. My whole family is crazy about them but when it comes to me. I look more intrested than them. Not too many things are happening at the time except that I rarely see my father because he is in Brazil. I was born on March 17,2001 in Anchorage, Alaska, I have one brother who is older than me with my mom and dad. I am very talented at soccer and swimming, but not in math. I love reading and learning science with my awesome teacher, I also like puzzles that are almost impossible. Now that I have told you about my self, I will ask you a faw questions. Do you play any sports? Do you have any brothers, or sisters? What do you like to do on your free time?

Переведите пожалуйста, а то у меня какая то ерунда получается!!
