Why? Because blood is thicker than water, thats about why. Its easy to cut of friends (water), not so easy to just forget family (blood). People sometimes think that just cutting family off is the answer, to only find that they then suffer more emotional pain and turmoil for their actions to removing family from their life. Talking is often the answer, though that requires two people, an active discussion, and keep yelling out, and respect one anothers opinions.
