What a coincidence. Only the other day I asked the missus to put the loo rolls on so it comes over the top. She said I was being b****y ridiculous and it didnt matter at all.
Im glad to see im not the only one. I always have it coming over the top.
It can be the cause of disagreement... I knew a girl who seemed to think it should be kept ON THE FLOOR! Every time she was over I would walk into the bathroom and see the toilet roll sat there on the floor. I would put it back on the holder but I never really had the nerve to ask her why, and to this day I still haven't figured it out.
Some people think that sitting on a "european" toilet pan is a very bad posture for expelling waste. Maybe leaving the roll on the floor made her reach for it so improving her expulsion technique???
