Be sure to warn your friends about bathrooms in Chile; they need to provide their own toilet paper.
I can sometimes be a bit pig-headed.
I didn’t realize that information that I was taking for granted, was critical to my compatriots.
My travel companions, who arrived in Chile several days before I did, didn’t know that you need to often bring your own toilet paper to bathrooms in South America.
It’s always a good idea to warn travel companions of bathroom situations so you aren’t getting angry texts in the airport… Angry texts from those who managed to bring their cell phones into the bathroom, but not a scrap of paper.
Also, if you want to learn how to protect yourself from injury in Chile, don’t do this.
