Telling something to someone that you know is incorrect information is not a mistake. It is a lie and deceit.
Have you ever lied before and then regretted it later? would you call it a mistake to lie in the first place?
Lies are most often mistakes. The terminology is not mutually exclusive. But using the term mistake has a distancing effect. One of the greatest Non-apology apologies is to make a claim that mistakes were made. It gives the air of Apology without truly owning the responsibility of the mistake. Sadly i get the sense that Porky is employing this tactic. There doesn't appear to be any acceptance that the responsibility for the bulk of the screwups lies with the OP. I suspect he still views himself as a victim of circumstances that forced him to justifiably commit bad acts. Only by owning up to the true nature of the Intentional bad acts will the OP earn any respect here and self respect in the long term.
Ok, im going to try my best to make myself clear here :
Im sorry! Im so sorry!!!! I never meant to lie. I thought at the time I was doing the right thing, but I was wrong and made a mistake. I'm so sorry and i want the WORLD to know that I am SORRY!!!! I was under pressure, I was not entirely sure what exactly to do, I messed up and im SORRY!!!!!!!!
Is that a sufficient apology?
