Faults

Can one truly comprehend their own faults, or are they just in denial. I want to know what my faults are, please tell me. It may be harsh, but fucking tell me. In attempt to shed some light for someone, I was blunt and expressed to someone their own fault and instead of accepting it, they turned their fault onto me. I guess, that was easier to do, because in doing so, then they didn't have to own it, it was now my fault to own with them. That being said, do I own that fault truly, or do I deny it being they were just upset at hearing their own fault. In doing so, I could just be doing the opposite of what I just said one should not do. Do I accept it for what it is or just throw it out as a mistake? Wow.... that was an existential (sp?) moment! In many ways, I feel I know my faults since I have pesimestic views on many things, including myself and my abilities (that way I am never let down...). Although, I feel I can see others faults quite clearly, although with my "issues" (diagnosed or undiagnosed) it depends on the person. I tend to idolize certain people and they do little wrong... others do many things wrong and to me, that is okay and I can accept that; they however do not (when they hear it from me, of course). Those people, I tend to have no feelings toward and my thoughts for them waver on a day to day basis... whether I will tolerate them or not. Hmmm... it must suck for those people. I'm pretty harsh sometimes.
