Imagine a culture in which the old are venerated, then think of one in which they are thrown away. These are very different scenarios. In the first, seniors might live with family where they are cared for, loved and treated with respect and dignity. In the second, seniors are ignored, abandoned and left by the wayside, despite an inability to care for themselves.
Now consider how the very young and the disabled are treated. Are babies nurtured even if they have obvious issues? Are toddlers who are deaf or blind left on a rock in the middle of the forest or is there some system in place to care for them?
What happens when someone is injured and is then permanently disabled? Does the family provide food, shelter and love or leave them behind when they migrate?
Your task is to write a scene in which one of these populations takes on an important role. Don’t tackle all three, however. Choose the one that you feel the most comfortable writing about, perhaps one that you know intimately.
Begin by making a list of possible reactions, both positive and negative. Where will the story start? Choose a point of action designed to establish society’s POV. This might be a tense scene or one of love. It might show someone being abandoned or someone being nurtured.
Dialogue is important so that readers hear how the community thinks. There need not be total agreement between members. For example, someone might want to keep a disabled child, but the cultural rules forbid that to happen. Conflict ensues.
Have fun with this one.
