Generally I'm not too fussy but I agree with Shangrala about the toilet paper.
1. Toilet paper has to roll from the front.
2. I have a method of organizing the dishes in the dish washer.
3. Lights out when someone leaves the room.
4. Flush the toilet when you're done your business - grrrrr
5. Keep your socks together - big problem in my house
6. Wash my hands before food preparation or after touching meat/eggs.
7 Laundry room door must be shut to prevent the 'sock stealing fugitive' from striking -which is why there a #5.

I think these are all reasonable and I'm easy to live with. I used to be more fussy about cleaning, but have become tired as the girls are getting older. I'd rather be more relaxed than having everything perfect, but do appreciate an organized house.
