Hi! My name is Daniel (though my friends call me Dan). I'm 14. I've got a Mum, a Dad, a brother, a sister, two aunts and two uncles, one grandmother and one grandfather who all live in Almaty. I'm the youngest. Sometimes my brother tries to boss me around but it's OK because I can sit up late watching video with him or go of somewhere for the day with him.
My hobbies are sports and music. I would like to have a younger brother; I want to have someone to have fun with, someone to take out to football with me. My brother Mike doesn't always share my sense of humour and he doesn't have time to play chess with me. He spends to much time with me. He spends too much time with his computer.
But I confide in my elder brother like a friend. I have confided in him about many problems. He's been trough with the same, so he understand.
I think it is common with most young people to spend some time outdoors. It's important for us to meet, to talk about things, to walk around just "to see what's going on", to go to disco clubs. My elder brother is allowed mor freedom than me. He can earn his pocket money by delivering newspapers 3 times a week. He usually gets enough to by the records and CDs he wants without asking the permission from his parents. If I go out, my psrents like to know where I'm going, who I'm and what time I coming home. But that's fair enough.
As most teenagers I spend my after school hours at home watching TV or listening to music; reading, doing domestic chores or playing computer games with my sister Liz. Liz a student. She is going to be an economist.
On the whole I get on well with my sister Liz. Last year she bought a Walkman for me on my birthday.
Of all my relatives best of all L like my Granny who is still fond of sports and adventures. On her sixtieth birthday she went mountain climbing. On her seventieth birthday she went on a trip ti Siberia. We all wonder what she will do when she is 80. Her favourite saying is "Health is above wealth". переведите пожалуйста но не пользуйтесь переводчиком.
