In my own bathroom, I always have it facing the uh...user. In the downstairs bathroom, though, it's usually facing the wall. I get all obsessive compulsive whenever it is and fix it whenever it's that way.
The toilet paper should not be facing the wall at all. What does the wall need it for (besides holding it up)?
Heh, I actually once considered making a thread just like this one.
Pointless.
If you find it pointless, DON'T POST, AND IGNORE THE THREAD.
