None—unless one of your cheerful sorority sleepovers takes a drastic turn into horror. These things do happen sometimes. One moment, you'll be having a pillow fight in your underwear, and then, bam. You're taken out with a machete by a guy in a plastic mask.

Look around. Have you just moved into a new house? Has the power suddenly decided to go off? Is there creepy background music warning you of your immediate doom?

If any of the above applies, Shmoop humbly suggests running running for your life.
