Neo has called her out wanting to know ---why--- she did it to him when they were such close friends. (I'm not going to go back and qoute it since it was said a few times. Like "Ijust want to know why you did it".) I believe anyone would want to know that. Even after apologies we, as humans with emotions, sometimes can't get over what another person has done to us. Like if the love of your life came home and said "I've been banging people behind your back since the first day we started dating." followed by a "but thats horrible of me, I'm sorry." the initial response would be probably accepting the apology since you haven't had time to process it.
But then you'd start thinking about it, processing it, stewing over it. And eventually that sorry means absolutely nothing becuase there was no reason why. And thus it gets brought up all over again in a nasty conflict of personal attacks and an audiance :/.
We all know it hurts to be betrayed and taken for a fool. To me, it seems, the OP was intended as a "for your own safety" with an underlining "I just want to know why you did it." and since many people tend to stumble with their lies by not maintaining consistancy infront of dozens of viewers, maybe thats why he brought it to the public.
All of that is my own stipulation though from a psychological stand point so I'm not talking for anyone. Everything, to me, seems moot now besides the fact that she:
A. Passed off exact doubles of his gear, that weren't his becuase they were signed different, to him. As another poster said "why did she 'borrow' his if she had her own?"
B. Did indeed lie about the fact. And panicing because you have property that isn't yours so put on a very in depth ficade is not an excuse to me. They obviously were very good friends, good enough for her to have his account information. If it was me I would of purely said to his initial response of his stuff being stolen; "Lol its not stolen, I have it silly. I needed it and you weren't on so I borrowed it

I'll send it right back over."
Calm and rational typically stops blood baths of personal attacks and uneeded public attention from happening. I understand she said sorry, and I understand he took that apology. And a two month wait is a little odd. I can also see the point of waiting when hes not completely angry about it to post as well. Becuase when we're mad we can't control ourselves sometimes, and one bad move may of ended up in him unloading his arsenal of personal information against Mish. Which as he said in the first post, he didn't want to do that.
Maybe it took him 2 months to cool off? I dunno. Either way, those two things above have either been passed over with lame excuses or just haven't been answered at all. Evasion of response, to me after working with inmates, has always meant guilt. That may not be the case here, as everyone is right, it is very he said she said. But I also know people who have the conversations saved and could post them but are chosing not to as they don't want to get involved and they just say exactly what Neo has said. So I am more apt to question what happened directly in that conversation only. And that is A. and B.
