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.
