One of my aunt's friends. She says using a lot of water is wasteful, so she only showers once a week, and even then, she doesn't use any soap. She doesn't brush her teeth and only washes her clothes in water(after several wears). Anyway, she was telling us toilet paper is bad for the environment. She said she didn't use it unless she had diarrhea.
I made sure I didn't sit in the same chair she did for the rest of the visit.
