{{{{{{{{Kimmy}}}}}}}}}} Some of my thoughts:

Bearing a grudge gets quite heavy and robs us of energy needed elsewhere. It will also fester inside and poison our actions and our thoughts. It will stand in the way of our own personal progress and robs us of peace, love and JOY.

"You hurt me once, shame on you. You hurt me twice, shame on ME." Which goes along with "You can forgive but you don't have to forget." To forget is to put yourself back in harm's way.

The flip side to that is, when you say "I'm sorry" it's much easier than saying "Please forgive me." "I'm sorry" can become an unconscious habit. Asking "Forgive me?" takes thought, sometimes a big gulp of pride and acknowledgement of your own wrong deeds... Accepting Responsibility. A person is a lot less likely to re-commit a hurtful act or word after asking for forgiveness.
