“how bout just washing the one square out.””
She can’t deny that reusable toilet paper would be more “green” than using even one square. Even better would be quick-drying underwear that could be used as TP, washed out, quick-dried and worn for a continuous month before being “recycled” into a new pair. If it also could be designed as a dual-purpose face-wipe, all the better. I can’t see how Sheryl could possibly raise any objections to this super-green idea.
She could also save paper by doing only free concerts - that don’t require tickets of any kind.
