MY FAMILY
My name is Svetlana. I am 16 years old. My family is a small one. There are three of us in the family: my mother, my elder sister and me.
My mother is a manager of the firm. She is fond of her job. And in spite of the fact that, she is always busy she finds time to spend with us. We often spend evenings together. Sometimes we go to the cinema. I like films very much, and my favourite one is "Analyze that". It can seem strange, but I have seen it for many times and whenever I have a chance to watch it I don't miss it.
My sister's name is Natasha. She is already a student. She is 20. Natasha studies at the Institute of economy. I think she will become a good specialist. She studies a lot and she is an excellent student. I am so proud of her.
Natasha is tall and slim. But what I like most about her appearance are the dimples on her cheeks. She has long black curly hair. She is very pretty.
Well, as my mother works very hard and has a lot of things to do, my sister and I try to help her about the house. So we share our house chores. I usually tidy up the rooms and sometimes cook something to eat. Frankly speaking, I am not very good at cooking, but my mother doesn't think so. Maybe she doesn't just tell me about it, because she doesn't want me to be disappointed. But I think that everything comes by experience. I am an optimist by nature.
As I am a sunny soul person by nature, I love to have fun, to laugh, to talk and I like people with a sense of humour as well. I think that humour is one of the most necessary things for people. It is such a feature of character that everyone of us must possess, because it helps us to live better, to survive, to go through our daily problems easier.
Talking about hobbies, I would say that I am fond of reading. I can say I adore reading. My favourite writer is Remark, and my favourite book is "Three Friends" by Remark. I appreciate the friendship of these "three friends", their relationship, and how they care about each other and help each other out of the difficult situations. I think a good example of friendship is shown in this book. I also like dancing, and I dance much. I regard it as an essential part of myself, and I think it can be called a sort of a sport activity, as it helps me keep fit.
I also adore travelling. I think that it is a hobby of my dream. There are so many countries that I am eager to visit. I like nature and during my summer holidays I don't miss any chance to go to the country. And in the country I look forward to my coming back to the big city and going on my routine every day activities.
And talking about my daily routine I want to confess that it is not quite organized. And every Monday when I am awake I think I should start a new life. I honestly think that I must become well-organized and correct my daily routine. I make plans to go to keep fit classes, to do the cleaning and do hundred other good things. But then I remember that I have to call on my friend in the evening, and I put off my plans till next Monday. It is always better to start a new life in a week.
