Our characters might have brothers and sisters. If so, we have to define their relationships and how our character feels about the siblings.
For example, in some families, siblings seem to get along marvelously. This has a lot to do with how the parents treated them. If achievements are applauded equally, if discipline is handled fairly, and if comparisons never come up in conversation, then there will be no/little ill will.
In other families, it’s all about competition for parental attention and favor. Sons might be held in higher regard than daughters. Sons might get preferential treatment when it comes to borrowing the car, staying out at night, doing chores around the house. Girls might be subservient, only being able to use the car if the boy doesn’t need it, having restrictions that prohibit socializing at night, and having to clean the entire house, including the boy’s bedroom, before having free time.
Sons might be expected to learn to mow lawns and care for the car, while girls learn to cook, sew and shop.
You have to decide how to handle siblings in your stories.
Your task is to write a scene in which siblings interact with each other and with at least one guardian. This will require some dialogue, some description, some movement/change.
Have fun with this one.
