I am my works most difficult employee, and proud of it. Even my boss tippy-toes around me or I will strike like a Viper. If it is right it's right if it is wrong then you will hear it from me. I don't go with the crowd to be slaughtered. Push me and I will shove, kick and scream, get out of my way or I'll run you over.
....and if you think I'm kidding just ask Rockscrambler.
Well if you're looking at it like that, then yes I'm one of the "most difficult" people there too. But there's a huge difference in trying to make sure people are doing things right and doing things half assed then making a stink out of it when somebody points it out. If wanting things to be done correctly makes me difficult, then color me difficult!
