Ever been to Mexico? You know that used toilet paper goes in the trash, not the toilet. The cleaning lady empties that for you tho. Except, the last time I stayed there, I did have a toilet problem and told the owner that I had been doing that, and she said "that's gross." They were new owners and may not have understood that then. Take some baking soda to sprinkle on used paper if you want.
Your wife can use the balcony as a Widow's Watch and look for you leaving and returning.
Yup. We're both seasoned enough travelers to have been to plenty of places where the plumbing and sanitary systems are decidedly less robust than in the States. Spending a month in Nepal will make many other destinations look quite luxurious.
