Goodevening every body! Let me introduce myself. My name is Pham Ngoc Anh but I'm a boy ^^. Now, I'm thirteen years old. My birthday is on the Second of the December. I live in An Vien with my family: my parents, my younger sister and I; but I also live in Di Che with my Maternal Grandparents. I go to Di Che Secondary School. At School, My Favourite subjects are Math, English, Phicsical, Chemistry. I like them, because, I think they are not only very important but also very interesting! However I don't like some, example Arts. I don't like Arts, even I hate it, because, It's very very diffucult, and, I can draw anything well. I have some hobbies. I like sports but I do not have much time to do, so I rarely play sports. My favourite sport is badminton. I like it, because of....because of no reason. My favourite game is chess. I like chess because it makes me more intelligent, and gives me a large view, about the game and my life. I started this hobby when I was ten. My mother taught me how to play, and she shared her experiences. And, I soon adored chess. I shared this hobby with my best friend, his name is Tai. At first, he didn't know how to play, so I taught him. He soon liked chess, too. And now, he plays better than I do . Now, we often play chess whenever we have free time. And this is my last hobby. You see, I like reading books. My favourite kind of book is novels, which're about some characters's lives or parts of their lives. Do you know, I always read books when I am lonely and stressed. Reading books makes me feel better. That's something about myself. How about you? Please introduce yourselves!!!!!!!!
