Winter is Coming

When I get upset I call house rules on no paragraph necessary. Don't judge.

When it comes to workspace politics, I wash my hands of it.  I wasn't born with a scheming mind on how to blame my mistakes on others or ways to self-promote at the expense of others.  I was always brought up to own your mistakes, and work as a team to help others.  Apparently, I am one of us rare few that aren't snakes when it comes to moving up in the workplace.  I feel like Ned Stark of The Game of Thrones, and my head is on the theoretical chopping block because I don't put up with games, people who play them, or hiding any of the two.  I call them as I see them and it makes people mad.  I will keep to myself unless someone starts messing with me or it is blatantly obvious that someone is being extorted.  Because of this, I have been called out and shamed for a couple minor mistakes when this same person I work with has repeatedly made errors, repeatedly come to me for help, and repeatedly complained to my boss about my mistakes.  I can't understand a person like this or how they can sleep at night, but one thing I know for sure is that you shouldn't mess with me.  Not for any violent or psychopathic reason (although tempting at this point) but because I will call you out, take ownership of my mistakes, and leave you trying to blame others for your own.  Problem is that this person is good, almost flawless at that game... so how do I fight back? Let me know what you think, because I'm lost.
