You have seen me in a moment of human failure. I have no persuasive reasons to make you see me in the same light as before, and I do not even see myself in the same light. Failure tends to make one re-evaluate the contradictions between motives and actions.
Sometimes saying "I'm sorry, will you forgive me?" seems insufficient to reconcile our failures. I wish there was another magical phrase that could erase the pain we cause another. I suppose if there were, however, we would go around failing everyone we know because it could just be erased.
The pain I caused is not erasable. But because it's there, I am reminded not to make another mark on you.
