Blood is thicker than water. Family will always be there. Those not related ..... may fill in your emptiness upon knowing your weaknesses ..... or simply attack your weak point. However, there is a way to prevent yourself from being injured. 1st is ISOLATION where no one can hurt you. 2nd is DOMINATION where you get to rule others. Accomplishing the 1st trait sounds simple but requires enough courage to even face death. The 2nd trait will require you to be a being with little or no flaws. But, the most natural selection among all will be the 3rd trait, TRUST ..... which requires you to find real/true friends.
