     Hello. I am going to tell you about my favourite person.

     My favourite person is my best friend, Hoa. She is twelve years old. Hoa and I go to the same school and we have been together for seven years. Hoa is very beautiful. She has an oval face and long black hair. She is slim and tall. She is clever and hard-working. She is very funny, too. She often makes jokes and we all laugh.

     She is very fond of music. When she has free time, she often listens to her favourite songs from computer with me. At weedend, we usually go to music shops to buy new CDs. Of the famous pop singer, she prefers Lady Gaga but I prefer Katy Parry.

     She also spends an hour after dinner watching the programme "The World Here and There". She likes it bacause it widens her knowledge.

     I like being with her. We often do our homework together in the afternoon and she helps me a lot. Sometimes, she comes to my house for dinner. I also like her because I always have her shoulders when I cry.

     I love Hoa very much and we will be best friend forever.
