As a child of 7 years old I was relied upon to knock on the bathroom door a couple of times while my elderly grandmother bathed in the tub.
I would always knock and call "Are you OK" which came the reply "Yes" or "Almost Finished". One day I fell asleep and forgot my timed duty.
I bolted to the door late and when I knocked I got no reply. I opened the door to find the severed head of my grandmother sitting on the back of the
tub, body floating in the soapy water. The head turned to me and said,
" WHAT TOOK YOU SO LONG "
