This is quite a late fad addition to the list! I was wondering what would happen if Petrie mysteriously came to your house.
I would happen to hear a knock on the door. I'd open it up to find...nothing. But then, something starts to fly around left to right. When that something finally stops and I realize who it is, he would probably be scared of me at first, but I would just tell him that I'm friendly and I won't hurt him. Then I would give him a big hug.
Then I would invite him in (just as long as my rottweiler dog isn't barking at him!) Afterwards, I would probably check to see if I have any leaves or berries. If I do, I'll feed them to Petrie, and he'll likely enjoy them. Then I would ask him all the logical questions about him and his friends and...well, everything else.
What are your thoughts?
