Being bullied is something that can never be erased. Remember an insult stains someone forever, you leave your mark. Even 20 years later you'll find the person remembers, still feels bad at the memory, what you said. You can say sorry but the trust is gone. You can crumple up the paper. But when you feel bad and straighten it out, the crinkles will still be there; the scars you made will never go away.
