I've asked this question before and been surprised by the results, now I have access to more weirdos it's your problem:
It is the middle of a Sunday afternoon. You have nothing on, and aren't expecting visitors, deliveries or post.
Unexpectedly, there is a knock at the door.
Not naming options to skew votes but...
I think there's something fundamentally baffling with the way most of you think.
I would be less surprised to find a fairy on my doorstep and more disappointed in myself having opened a door, found something on my doorstep and then jumped to the conclusion that fairies are real merely based on how the thing looks.
A walrus would be surprising none the less, not because of the odds of one ending up on my doorstep, but because of the fact that there is a large and deadly pile of muscle and fat with giant teeth that could kill me with relatively little effort. I'm not thinking of how it got there, I might be a doors thickness away from death.
