Hi paper, I thought my mom was the only one!! lol... I wonder how many other people do this too? Interesting.
Anyway, I dont think your sink thing is unreasonable at all. When you really think of all the germs that we all pick up on our hands, and come on its your kitchen sink where you prepare food for your family. Let them go to the bathroom to wash their hands. When I was in nursing school at U of MO before I changed my major to Psychology I took this class that had us wash our hands for one minute then dry them and hold our hands under a black light and you would be amazed at the germs that still were on our hands. After that I became more vigilant with the hand washing; as they say wash for 2 minutes and dry with paper towel not dish cloth or bath towels as they hold germs.
My ex-husband was completely OCD...drove me nuts. He totally scrubbed the lining or whatever it is that you call the enamel off of our bathtub by scrubbing it everyday. He vacuums in straight lines everyday and after he would vacuum he and I would have to pick up the dogs (we had 2 shih-tzu's) and carry them around the house so as not to get paw prints on "off limit areas". The dogs even learned to jump from the couch to the recliner and then wait for one of us to carry them the rest of the way.....He had a whole list of chores that had to be done everyday. It was nerve wracking to say the least.
I collect fingernail polish probably have 300 bottles at least. Oh and I cant spend pennies, I have to save them for some reason. I have big jars full of pennies.
