In Toni Cade Bambara's story "Raymond's Run," Squeaky's family responsibility is to care for her disabled brother, Raymond. Due to Raymond's developmental disabilities he needs constant care to keep him safe and out of trouble. Squeaky takes this responsibility very seriously so that her mother can concentrate on caring for the family home.
Raymond tags along with Squeaky wherever she goes in their Harlem neighborhood. While she practices her breathing and high-stepping, Raymond can be seen prancing along pretending he is driving a carriage. When Raymond runs through the pigeons or into the puddles along the street, Squeaky is quick to correct his actions so that she does not get in trouble at home.
If the other children mock Raymond for his large head or mental deficits, Squeaky quickly comes to his defense by fighting the perpetrator. She is a loyal, caring sister who looks out for her brother's well-being.
