Sorry, not to be picky but can I grammatically correct your letter as there’s quite a few grammatical errors in there (not trying to be offensive, just trying to help!)
Is it supposed to say Angel’s rather than angles? If so it should read this…
Dear Mr. Black,
I know you think it was the Angel’s, let me just say this… the Angel’s had nothing to do with it.
But please remember, we play this game better than anyone and we will destroy you.
