it's like the eye of a duck

I'm not married and I don't live with a significant other, I live with my 85 year old father. One of the big reasons I live with him is that if I didn't, the house would turn into those situations where the Board of Health would come in and condemn the place as a bio hazard. Quite simply- my father doesn't see dirt. It never impinges on his conciousness. I've done tests to see how long it takes him to want something cleaned (like the sheets on his bed- after 8 months I couldn't stand it anymore, they were black with dirt and my father didn't care a bit.) My father's contribution to the cleaning is taking out the garbage (and I had to yell at him one time when I came home and found him sorting thru the contents of the kitchen garbage can on the kitchen counter just in case I had thrown away something that he thought should go in recycling) and cleaning the cat box. He originally also volunteered to wash the dishes, but then I found out that his idea of washing the dishes was to wipe them down with a paper towel and cold water and as long as he didn't see any dirt they were clean. Remember, he doesn't see dirt....and I was wondering why I was having all these violent intestinal issues that I'd never had before....we now have a dishwasher that I am in charge of. I've decided that living with my dad is like living with an 8 year old boy only without the ability to learn new skills. So basically the division of labor is- I do it.
