You win, Granny!
(Background: it is well-known in certain circles that, of the two of us, Mr thalarctos is the domesticated one, while I am totally feral [h/t George]).
While I believe there is no afterlife, I'm certainly prepared to admit there is a possibility that I am wrong, and such a thing, however unlikely, could conceivably exist.
Should there be such a thing, and should my mother's mother be able to see me now, she is, no doubt, laughing her ass off at the rebellious 8-year-old who refused to learn to make a bed properly, and insisted that, when she grew up, she'd never make another bed in her life.
On the other hand, I'm making so many beds nowadays that my mitred corners have become something to absolutely die for (not literally, no!).
