There is no one like my friend Marty in my middle school or on Earth. She's really unique. Adults think she's pretty cool, too. They can only shake their heads as they witness her doing one amazing thing after another.
I adore Marty because she is special. No one can match her intelligence. She is kind enough to sit and listen to people, even when she knows they are not as smart as she is. I think some of our classmates are jealous of her. Whenever any of them have a problem, Marty takes charge and steps in to help, but believe it or not, they resist her help. They just don't understand her greatness like I do.
