Mine doesn't go on the roll anymore
It has to go in this little shelf/cabinet thing above the toilet as I have a 10 month old whose favorite pasttime is grabbing the end and running to the living room with it (I guess I can be glad she doesn't stuff it into the toilet).
And yes, the simple solution would be to shut the door, but that doesn't work in a house with a 2 year old who's just tall enough to open it, but not tall enough to pull it shut behind her.
