Things I learn from horror:

Say you're a 15 year old kid, and there's a monster living in your closet. Every night, the monster creeps out (it's been living in the crawl-space) and mutilates you while you sleep.

Do you:
a) run screaming from the house after the first incident, never to return?
b) start taking kitchen knives to bed?
c) continue sleeping in room with monster and bandaging wounds so no one can know?

(Hint: the story says C.)
