Family is one of the most important institutions in society. It is the duty of blood to out for blood, even when they make foolish decisions.
Many of the Lufkins have long been known for their foolish decisions. While your wealth, your name, and your blood have offered you some protection, we can no longer ignore the slights your cousin and sister place on the good families of our world.
While there is little hope that they can ever live up to the blood they were fortunate enough to be born with, if you value the safety of your family and those it holds most dear, you will remind your degenerate blood of the foolishness of slighting their betters.
