Много баллов!!! Помогите пожалуйста написать сочинение на британском языке о вечеринке.

Let me introduce myself. My name is Stepan. Im 15 years old and I study at the 9th form of the local high school. Im a sociable and outgoing person by nature. I like all kinds of parties and celebrations. Im always full of new ideas and people call me a party animal. Im rather good at planning and organizing different events and I like being in the center of attention. One of the recent parties I have arranged was my cousin Peters birthday. He is two years younger than me and his family has just moved to our town. He doesnt have many friends yet, so Ive decided to help him with party arrangement. He agreed to invite some of my best friends, because the more people, the merrier the party. The flat, where he lives, is rather large. There are three bedrooms and one living-room. We chose to decorate the living-room. Peters mum prepared some delicious salads and ordered three pizzas. At the nearest supermarket we bought several boxes of fruit juice and two large bottles of Cola. We thought that should be enough for everyone. It was going to be a mixed party, so not only boys, but some girls were also invited. While Peter was helping his mum with cooking, I decorated the living-room with colorful balloons and wrapped his present. I also thought over some party games. When the guests arrived, we together sat at the table and had a quick bite of different goodies. After that, one of my friends played the guitar and we sang a song to congratulate my cousin. Then, we played a round of Mafia, as everyone liked this game. After that, we turned on the music and danced. Luckily, the room was quite large, so we had lots of space. I could see that Peter was having a great time and that мейд me happy.
