Number Seven

You are about to open the door that has a light on behind it, but you think you see a shadow moving from under the door.  Afraid of what may be lurking behind door number one, you pick door number two.  You open the door and step inside.  The moonlight is streaming through the broken window directly in front of you.  You notice all the guano on the floor and look up to see bats lining the ceiling.  You move quietly, praying that you won't wake them up when you slip on some more recent guano.  You fall to the floor, covering yourself in even more guano.  The bats begin shrieking like a wounded cat, as they begin waking up.  You cover your face with your hands as they fly right at you.  You receive a few pecks, and then they fly away into the night.  Your heart is thudding violently at this most recent encounter, but you have no choice but to get up and try to get away.  You walk to the window and look outside.  You are surprised to see that your friend is still out there.  You wave at him and he looks surprised to see you.  Then, violent spasms roll through your body.  You fall to the ground and watch as your hands grow pale in the moon light and fangs grow inside your mouth.  Once the pain stops you stand up and try to give the thumbs up signal to your friend.  He goes ghostly pale and backs away, running down the road.  Your new sense of smell sniffs the warm scent of flesh blood and you turn into a bat and fly out the window after your friend.  

I'm sorry, you have become a vampire.  But really, when has going up the stairs ever been a good way to get out of a house?  Maybe if you'd been a little brighter you'd still be human.
