Dear Thomas dickens,
I am writing you to tell you how sorry I am for my brash comments about you yesterday. I had a lot on my plate and I was unable to hold my tongue. The things I said were out of anger and stress and though I know that that is no excuse, I still ask for your apology. I hope we can put this incident behind us and I do promise to not let my temper get the best of me next time.
Sincerely,
Jonathon
