What is the theme in Sudden Fiction International: Sixty Short-short Stories by Robert Shapard?

A recurring theme throughout Sudden Fiction International is the disappointment that accompanies aging. This is a theme that transcends nationality. All people grow old, and as they grow old they discover that they have also grown obsolete. This is most pointedly presented in the story At the River, in which two Maori fisherman must come to terms with their lack of utility. One determines proudly that the young should fish for him; the other doggedly joins the younger men and dies trying to catch eels. It is worth noting that another story, an American piece called Lost Keys, also uses fishing as a means for revealing a character's deterioration with age. Perhaps as fishing is an innately human activity - one we have engaged in for centuries - it is a classical driver of themes and action.
