letter to co worker who got mad at me ha ha

Billy,
First off, I apologize if I uttered any falsehoods about your work ethic or performance that may have insulted you. Those were not my intentions. I was under the impression that our correspondence was a mutual heckling, absent of any malice, serving only to comically point out minor departmental issues. But apparently I was mistaken. However, after reading your letter, I feel my misconceptions are justifiable.
In your letter to me, you claim that your previous notes were "attempts to resolve departmental errors", in which you included your own barrage of slander, which were often tinted with a brash, and sarcastic tone. It was through this tone where I formed the perception that you were writing your notes with humor in mind. Moreover, you then state that I took your attempts as a "personal attack", which then drove me to maliciously lash out, writing slandered notes to you as my outlet for my anger. This is where I find an inconsistency in your letter.
Throughout your letter to me, you portray yourself as the victim, writing with an indignant tone as if I was constantly maligning you. However, when you mention that I "misconstrued" the reality behind our correspondence, there suddenly becomes two victims. But how am I a victim? Surely someone doesn’t feel "attacked" for no reason (since that’s what you claim I misconstrued your letters to be). This indicates to me that you are as guilty as I am for attacking character and uttering falsehoods, otherwise if you were not attacking my work ethic and character, I would have no reason to feel "attacked", as you claim I was.
I would love to talk to you in person to sort out any grudges that may have formed between you and I. But again, this whole time I had the understanding that you regarded our correspondence as harmless, harassment’s. If you would like to end our notes to each other, that’s fine, just say the word and I’ll cease writing immediately.
Sincerely,
Kyle Kennedy
P.S. I spoke with Jeff about this issue. He said that he never C.C.’d your letter to me, yet alone even talk to you….
