The sil I know about is the complete opposite of my wife so they could still have an unknown sibling.No OCD in that woman. I'm the one with a moderate level of OCD. She keeps a clean house, but doesn't mind having 14 different hair products on her vanity. Mine has a bottle of hand soap. I don't think she has ever played a video game...in her life.
My thing with the dishwasher is that it reminds me of trying to keep my toolbox drawers organized. My toolbox is just a tad too small so I have to keep everything just right to be able to close a couple of drawers
