Read the text "My family".

Семья.png
I have a large family. My father is 57. He works as an engineer at a plant. My mother is 55. She works part-time as a nurse. My younger brother is a student of economics. He is going to graduate next year. I also have an older sister. She is married and lives with her family in an apartment house not far from us. They often visit us. Her daughter Lena, my niece, is a very talented girl. She plays the piano and writes interesting poems.

I am married. My wife Olga is a schoolteacher. She teaches mathematics. We have two children, a boy and a girl. My son Victor is six years old, and my daughter Anna is three years old. They go to a kindergarten near our house. My wife picks them up on her way home from work and takes a long walk with them in the park. My mother looks after the children when we work late, and my mother-in-law takes care of them on Saturdays.

We live in a large house with a nice garden. There is enough room for all of us, and I even have my own study in the attic. It is small, but I like it. There is a table with my computer on it, a chair, and a book shelf. I spend a lot of time there working with my papers and studying English.

We have a lot of relatives. My aunt and two uncles live in a small town about 60 kilometers from my hometown. Their children, my cousins, are about my age, and we communicate often. Every year the whole family gets together for Christmas. We prepare a huge Christmas dinner, and there are a lot of presents for everyone.
