Good for you to stand up for yourself and your fond memory of your grandma. Good for you to give her chances to undo wrongdoing! I do believe that being a person who knows what right or wrong drove you to reach out to her (not.your anger). Forgiveness Is the most confusing concept and holding grudge only affects you not her. I hope that one day you can forgive her misjudgement and free yourself for any residual resentment. Thank you for your story. It did have an impact.
