Squeaky's world revolves around her brother in a big way. Because Raymond is mentally disabled, Squeaky takes on the role of being his protector. Although Raymond is her older brother, Squeaky takes special care to keep her brother safe. She shields him socially and environmentally. When the other children in the neighborhood try to make fun of Raymond, Squeaky often comes to his rescue.
While training for her races, Squeaky is careful to run a certain path in the neighborhood so that her brother doesn't get lost or wander into the street. These are not things that a typical tweenager would consider. While many girls her age are into music and fashion, Squeaky's main concern is the safety and livelihood of her disabled brother.
