I have been told by my grandmother, that if you have five best friends in your entire life then indeed you are a very wealthy person. Many people go through their whole life and never have one best friend. She went on to add a real best friend is there for you no matter what, knows all about you, all the good, the bad, and the ugly and loves you anyway.
A best friend is for life and will never turn on you. My grandmother added, with each generation it becomes harder and harder to have a best friend.
With the devil loose on the world he is doing all he can to break up any happiness that you may have found. When you have a best friend the devil goes to work to destroy that good relationship. We all learn that is why a real best friend is so rare.
People use false justification as a reason to turn on a friend or a loved one.
