"To err is human, to forgive divine."
I am not divine.
I am human, and I have always understood that that applies to all of us, that there are many times where I need to be afforded grace, and forgiveness for my own mistakes.
I don't always see what mistakes I make, as I make them. I sometimes have to have those mistakes pointed out to me. When they are, I try to reflect on how I could have done better, and how I can go about making amends.
What I try to make sure I do not do is double down on my choices or behavior, or try to turn it around on the friend that I hurt, and make it about how them bringing my mistake to my attention was hurtful to me. If you bring me your hurt, that I have caused you, I will not then turn around and tell you how hurtful you're being in calling me out.
I can't grow from my mistakes if I don't know about them, if I am not told what I have done. That also applies to all of us. If your friend brings you their hurt and their sorrow over something you've done, the last thing you should do is make it about your feelings. If your instinct is to make it about your feelings, that person you've hurt? You're just demonstrating that the pain you brought them isn't important to you. That they don't actually matter to you.
Once upon a time, I would have begged someone I called my friend to please care. But that was a long time ago. If you demonstrate that I don't actually matter to you, well... You only have to tell me once.
