In the beginning of "Raymond's Run" by Toni Cade Bambara, Squeaky is only concerned about herself and her handicapped brother, Raymond. She is very competitive and brags about being the best runner in town with the exception of her father. Squeaky is also especially protective of Raymond and is always ready for a fight with anyone who makes fun of him. She is easily irritated with the other girls in her class, specifically Gretchen, who will be her main competition in the May Day race and who, as Squeaky says, "...talks about me like a dog" (Bambara 4).  By the end of the story, though, Squeaky realizes Gretchen actually is a pretty good runner, and both girls have a new-found respect for one another. Squeaky also sees that Raymond has run right along side of them on the other side of the fence, and she thinks about possibly partnering up with Gretchen to train her brother. In the short span of the story, Squeaky has matured considerably.
