I had to help the old couple lift up a flagstone lately. They were unblocking the pipe to the cesspit or some such. They told me not to dispose of anything into the WC.
I have of course performed hygienic acts on myself. Where else would I but the paper?
In my dream I went to the loo. Maybe I heard it bubble and that prompted the dream. In it a foul of filthy paper was coming up. reminds me of what happened in China.
