Most people do this and I don't know why
(The following is an example of what not to do)
I confronted someone with a lie they had told everyone. It wasn't even a big deal, however, I'm looking for patterns. When said person was presented with the counterargument by the third party, the proceeded to deflect by pointing out something potentially awful about the third party. I had stated that the third party discussed how the friendship between them and this person was terminated. Simply put, he was bothersome and had interrupted the third party's girlfriend's sleep by being relentless and needy; to which the person rebuttals with "I don't even have his GF's phone number". I stated that it was conveyed that part of this onslaught of calls was via Facebook, to which he had no response. Of course not.
Now if you're defending yourself, don't just assume you know more than you do, and certainly don't state which mediums weren't used unless you're prepared for a follow up. Every piece of information offered unprovoked just serves as a clue -- well if you offer up some information willingly, why not other information? Especially if it's so similar in nature... Such as pertaining to the method of conveyance... Just odd.
However, while being accused of telling a story that may have not been true, the person decided to out the third party as being a very young waifu enthusiast. To which I noted was concerning, but had nothing to do with the issue at hand. This is deflection and a distortion. He remained friends with the third party after witnessing questionable behavior, so why would he use this information to sway my opinion about the third party and make him seem less trustful? It wasn't a big deal when he witnessed whatever it was that he witnessed. But... He knows I heavily frown upon that type of degeneracy. Nevertheless, this doesn't change the fact that he lied to me and everyone else about something so small. Something that he does to everyone... Incessantly annoying actions that put people off. He does this to me, he does this to other people, and people do not want to engage with him because he is needy and clingy.
My biggest question is why would he think that I would buy in to his shenanigans when I'm already aware?
This is weird to me.
This is not something that one should do.
Being honest is better.
Being a good liar is more favorable.
