I've recently read some very good advice:
"Always have a safety word installed with your loved ones, in the event that an evil doppleganger from another universe tries to take your place."
I am known for taking precautions to reduce risk.
Assuming that evil dopplegangers will be waaayyy to busy to read through my meandering with poppets the safety word is "Renoir".
If I can't explain why - then it's a doppleganger who was smart enough to find and figure out the blog.
If I explain why and it still sounds fishy - check with the inhabitants of the House. They'll know.
But I wonder sometimes - why is it always the doppleganger that's evil, what if I'm evil and the doppleganger is good?
What if the doppleganger and I are both neutral?
Maybe we should both sit down for tea and discuss this . . . . I'll bake scones.
(Hmmmn . . . . . if it doesn't bake, it's definitely evil, and definitely a doppleganger . . . . forget the safety word - safety word plus Bake-off!)
