At the time, Greta was just beginning to understand that human relationships were pure folly, because nothing was ever perfectly mutual. One person always liked or loved the other person a little more than they were liked or loved, and sometimes it was a lot more, and sometimes the tables turned and you found yourself on the other side, but it was never, ever equal, and that was pretty much the only thing you could count on in life. This went for relationships between friends, siblings, lovers, spouses, even parents and their children.
