Sometimes life isn’t fair. Every wrong done to us will not be acknowledged. It’s a fact of life. Let’s face it, some people are never wrong in their own eyes. They lack empathy. Most acts scream this fact. You cannot expect someone that treats people disrespectfully to ever give a sincere apology.
So, what do you do? You forgive them for yourself. Then you forgive yourself for tolerating such behavior. Then you move on.
