I have a sister. She is 17 years old. Though she has recently graduated from school, she works in a cafe as a waitress. Her name is Tanya. She's probably one of the most beautiful girls in the world. She's of medium height, she has blue eyes and dark hair. She also studies at university. She wants to be a doctor in future. She's caring, kind girl, I'm sure she'll make a great mother when she bears a child. We've been friends since childhood, though she sometimes made me mad when she tried to make me do my homework. I really love her and hope her life will be happy.
