I had to replace the flapper in the 'terlet' today, as it had stopped
flapping.

I was right in the middle of the delicate procedure when Smokey arrived.
First she checked the shutoff valve where I'd disconnected the water
(replaced the float valve too) and proceed to stand on the seat and check
out the internal workings of the toilet. Satisfied that I had everything
under control, she supervised the remainder of the procedure from the
doorway.
