    I'm a junior high school student. My name is Sarah. I have a pretty aunt. Her name is Jenny. She is an actress. She must be at least thirty-five years old. In spite of this, she often appears on the stage as a young girl. Jenny will have to take part in a new play soon. This time, she will be a girl of seventeen. In the play, she must appear in a bright red dress and long black stockings. Last year in another play, she had to wear short socks and a bright, orange-coloured dress. If anyone ever asks her how old she is, she always answers,“Darling, it must be terrible to be grown up!”This is my lovely aunt. I love my aunt.
