On the very off chance I was a visitor at either of your houses, I'd not be able to resist folding a single roll of the two ply paper the other way so the tears don't match up.

My responsible adult has a similar mental health issue regarding toilet paper. Ditto folding towels in a certain way, even drying racks get rearranged if I unload the washing machine.

Mind you, try serving me a pint in anything other than a straight glass and see if accept the bugger...
