Sorry

Simply saying that you are sorry doesn't fix everything and even bargaining a manner to make things right might not do the trick. But to have feelings about remorse in the way you treated someone is the first step in your humanity.  And who says it is your job to fix everything.  The only thing that we can do is to try to become a little bit better a person than we were yesterday. To leave a little more joy in the world and less anger and pain.  So understand where you were wrong, the mistakes you made, intentional or unintentional and be sorry for them.  You can't control the reactions of others and who is to say what their emotional state is?
