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
Big question here, if vampires don't have a reflection, can a picture be taken of them?
I thought about taking the picture, but I didn't want to chance it not developing on the film, so I killed him instead.
We played 60 games of Battle Mode on Super Mario Kart and it was awesome.
I take up a Phoenix Wright pose, pointing at the supposed vampire, and loudly proclaim "Vampires do not exist!"
Come on in and let's play some Jenga.
I went back to bed. Aint no one got time for that.
...
Invite him in for tea, of course! That's tea as in tea, not tea, because I'd rather make him tea than be his tea.
Mock him as he stands there, because he can't get in unless I say so. And from then on, never go outside after dark ever again. Can't get me during the daytime, (blood)sucker.
Think to myself that I've stumbled onto the set of a Twilight inspired gay porn scenario.
