Im writing a story what should these characters be in a fight about?

IF they have 6 kids, there is plenty of material there. What kind of house to live in, where the house is, like city or country. What if one parent wants a minivan and the other wants an SUV. Maybe someone gives them a lottery ticket they win and they can get both!! Or maybe their great uncle gives them his big SUV, then there's nothing to fight about.Fiction is imagining People with 6 kids can fight about cooking, vegetarian or meat eaters. They could argue about how much allowance the kids get. Really when you write drama it helps to know the subject. Watch people with lots of kids and see what their problems are. Maybe you could talk to people at church who have more kids than usual. You could always put them in the Old West or in Hawaii...be sure you research the problems and happy things in these places.
