When "sorry" comes from the naked soul, accept it, otherwise be polite and move on.
In the end, I was only sorry I hadn't defended myself sooner. The worst day of Cory's life was the day he got power over me, the day I handed him the keys to my mind, body and soul. From then on he grew entitled and bitter, without challenge he became a tyrant to others and a prisoner to his own warped beliefs. Had I stood up to him, been stronger, I could have snapped him out of it. I could have told him to stop being so damn selfish and think of others, grow his empathy instead of his lust for dominance and cowardly need to keep himself safe at any cost. I think that's all I'm sorry for, everything else I did was defensive, defending myself and those who depend on me.
When the child-self says sorry, it is offered as a profound gift of healing for both. One can still remember the harm, yet the apology files it away, stamped it with a seal.
When self reflection allows the inner good wolf to see the deeds of the inner evil wolf clearly, "sorry" is the next step.
