A thought I wrote down on February 8, 2016 at 12:53 pm and just came across again now.
The balance is between having a relationship and having principles. If you must always be right, you will not have many successful, peaceful, happy relationships. No one likes a know it all. To keep a relationship going may require one to sacrifice principles. However, sacrificing all principles to keep a relationship means standing for nothing so you are liable to fall for anything. People with principles they feel must be upheld at all costs can resort to violence, fear and intimidation to control relationships within boundaries they can tolerate.
