What do you do? Choose wisely.
Invite him in for some tea
Just stand there and stare because he can't come in unless I say so anyway
Ask if he's accepted the Lord as his saviour
Beg to be turned in to a vampire. You've heard they have a good night social life
Poke him with a stick
Kill him with the stake I conveniently had next to the door
Take a picture and post it to social media
Go back to bed
Hug him
