Libby is so right in that when it is over it is too easy to unravel. We have dogs, cats and rabbits that all find it fun to unravel toilet paper.
That said, I don't have a preference either way. I won't change it around. I don't really even notice which way it is turned. I take about 2.3 seconds in the bathroom and toilet paper is the farthest from my mind, provided there IS some. Obviously if there is not it comes to mind quite quickly. LOL
I always find myself laughing when people start debating toilet paper. My friend's MIL would throw a fit and make a big deal if the TP wasn't on the holder in a particular fashion when she visited my friend. It caused huge fights between them. I mean, seriously, arguing over toilet tissue??
