Our family is not large

My name is Olga. I am seventeen. I am a school leaver. My younger brother is ten. He is a pupil of the fifth form. He looks like our father. He has brown eyes, short straight hair. He is tall and thin. As for me everybody says I look like my mother. I have the same blue eyes, a snub nose, fair curly hair. I am not tall and 1 am not thin. I am an ordinary girl of 17.
