You get used to things a certain way, but when you travel even the most common things are different. I could never imagine a roll of toilet paper without a tube in it, until I went to the Republic of the Georgia. The Russian-produced toilet paper was brown paper, like paper towels and it was rolled around itself. Because they don’t have tubes, most bathrooms don’t have toilet paper holders. And since the bathroom itself is entirely the shower, if the toilet paper were hanging on the wall, it would be soaked every day.
