What should I do now? I was young and dumb and I'm sorry.
Everyone makes mistakes when they're young. Why did you do it?
Well, I was young and gifted with a body back then.
When you are young you can make mistakes but it is good to realize it and to change. People would be more willing to accept your apology then.
True but I still think I was right to do it
When you apologoze for an action, you are also acknowledging that your action was incorrect. It's great to realize your faults so that you can learn from them.
