Please help me with this letter. How does it come off?

I was sitting here appraising what you wrote and thought well that truly sounds like a guy that's had a difficult time and has made some mistakes. but is now beginning to mature and grow as a human being, but then you say it yourself, you stole a quote from a movie, your a wonderful actor son, shame you didn't get the whole idea of sincerity and humbleness, most of us live and learn others just continue on the same path they trekked before, don't send her the letter its meaningless.
