Now, let's untangle this before my talk page becomes a battleground.  

 #Last August, I wrote a sarcastic note to a certain contributor who had reverted one of my edits. The person took it badly, qualifying it a "message full of hatred", which it was not - compared to some rude & crude exchanges one can read on Wikipedia, mine was more witty than anything else, and it contained no vulgarity.  
 #, (whom I never thanked, but do no), had understood my note in the tone it was written, and intervened in my favor. 
 # stepped in qualifying my message of “uncivil behavior”, which it was not. 
 #The person who had been offended by my words went on Serge Woodzing talk page & thanked him.  Again, the “message full of hatred” was mentioned, then  “that particular contributor” who was the “worst nightmare” Mr. Woodzing “had ever had so far”.  
 #Since Mr. Woodzing and myself had had a few sharp exchanges a few months earlier on a royalty page, I took his “nightmare” to be me.   

 Mr. Woodzing, this sounds more to me like a comedy of errors, and now you call me a “problem” & want me to apologize. I always apologize, but only for my faults.  In this instance, and in view of the circumstances, the time and the strange writing that made it sound as if I was your "worst nightmare", what fault did I make toward you that demands an apology on my part?  All I did on 14 August was write a single message to someone, not to you. When you chose to step in & qualified my message of "uncivil behavior" – which it was not -  you stuck your neck out because you had no idea why I had written that message. So I took your words as being aimed at me personally, hence my comment at Clotilde de France talk page.  

 All I can say is that I am sorry such an imbroglio took place and that it is disturbing you. I really do not want you to get sick over it, or over anything else, nor do I want to be one of your "worst or best nightmares".  

 Monsieur, je ne peux pas vous demander pardon pour une faute que je n'ai pas commise, et toutefois vous souhaite une bonne nuit pleine de beaux rêves.
