Addie the possum likes having both a younger and an older brother. She admires her older brother Torin, and how brave he is when he goes on his own to explore; she feels proud when she is able to help take care of little Buzz, her younger brother. One day it is she, and not Torin, who is asked to lead the family up the old ladder back to their home in the abandoned shed. On that night, she goes to bed feeling at once proud and very, very tired.
