I think you don't know what your house rules are until someone comes and breaks them so now I have 'no French bread in toaster' and 'no putting the heating to come on and off every twenty minutes'.
Also, dishes go in the dishwasher, not hand washed. If they must be handwashed, they are to be air dryed.
Obviously, hand towel for hands. It's really awful to use the tea towel meant for dishes for hands.
Toilet seat down, but I don't actually enforce this.
No noise after 10pm including washing dishes. This is the law where I live not something I've cooked up, but guests still break it.
No shoes if possible, but an exception can be made if people have problems with their feet or are very cold.
Window open after a shower, but not left open all day.
No making a huge mess - should be obvious, but apparently not to my guests.
Oven and microwave left on the setting you found them on.
Half-eaten food in the fridge to be covered somehow or put in a tupperware.
Pizza cooked in the oven on a baking tray. I don't care if the instructions say to put it directly on the grill thing!
