Here is a question. Suppose, you are a parent. You have 2 kids, both still very young. They are quarreling, both of them want the same thing, but mutually exclusive. And they're fighting it out. How do you solve the situation?
Does it make a difference if one is older/younger, or if they're twins? Does it make a difference if it's 2 boys, 1 boy 1 girl or 2 girls? Or is there any other factor that would influence your decision?
