I found the impact that siblings have on one another interesting. I have a sister and she has made a difference in how I live and act. It makes me wonder, in what ways would people be different if they had a brother, rather than a sister? Does it affect people other than the siblings? For example, does it affect the parenting style of the mother and father? Does it affect things like performance in school or sports, behavior, or relationships between siblings?
