It is easy to hold a grudge, ignore, vilify another, play the victim, be mean, rude or petty. However by doing this you are hindering YOUR evolution.
Who are you NOT to forgive?
What makes you so righteous?
Have you ever sought or been forgiven?
Have you never made a mistake?
Be gentle with others. Let go. Try again. Everyone is on their own journey, doing the best they can with the tools they have and believe it or not oftentimes it is not about you.
Demonstrate the tool of forgiveness by giving it to them. Perhaps the only reason you have this tool is because someone else gave it to you. - Misha N. Granado, MPH, MS
