This is the Smith family. There's Dad, Mom, older sister Emma, middle sister Charlotte, and younger brother Peter. They're a pretty average family who enjoys spending time together. But, the middle sister Charlotte has a hearing disability and she requires hearing aids to hear, even though she can barely hear with them.
When the family is watching tv, the subtitles need to be on so Charlotte can understand what is happening on the screen. In this instance, the whole family must be alright with the subtitles on because whatever happens to one member affects all (Turnbull 4). But of course, Charlotte's family doesn't mind at all.
While watching tv, Emma asks Charlotte if she wants popcorn. Emma has to communicate with Charlotte by using sign language. Emma likes helping Charlotte whenever she can. Because Emma is older than her sister, she feels increasingly responsible for providing care and coordinating services for her sister who has a disability (Turnbull 42).
When someone rings the door bell, the light above the door blinks so Charlotte can know when someone's at the door. When the family opens the door, their neighbor Thomas comes over to tell them that there's a parade down the street. But, Thomas doesn't know if Charlotte would like to go or not because she won't be able to hear the music.
Peter explains that even though Charlotte won't be able to hear the music, she has great vision. That she can still enjoy the parade without hearing it. He says that all children have various combinations of strengths and needs (Turnbull 6), just like me and you and your family. Then, the Smith family and Thomas walk down the street to the parade.
So, even though Charlotte has a hearing disability, that doesn't stop her or her family from having fun, doing things together, or living a normal life. The Smith family is like a mobile: the family is a system and what happens to one part of the system affects the other parts (Turnbull 4).
