I've posted before about my CKIA coworker who just has an obsessive-compulsive need to contradict me on every statement I make.
Most recently, we were all chatting and I mentioned that the pants I was wearing aren't my favorite, but I haven't been able to find a new pair of blue pants I like.
CKIA: "Those pants are NOT blue."
Me: Sigh. "Yes, they are. But that's the not the point--"
CKIA: "You're right, the point is that you don't even know your colors. Those pants are slate GREY."
Other coworker: "You know, CKIA -- some people might call that color slate BLUE. Which is blue with a lot of grey."
CKIA: "You're wrong too! I'm surrounded by people who don't even know their colors."
Some day I'm going to take a spade to her head.
