The one i love most is my mother. She is tall and rather thin
She is a warm kindly person with an oval face and a long-silky hair.
My mother loves us very much. She is used to staying up late and getting up early to earn money and take care of us. She is strict thanks to that we are educated into a good person.I will try to study well to satisfy my mother's faith.
