I remember, when I was in high school, a big group of us went camping by the lake. Little did we know that the lake was home to a psycho killer. Yeah, those babes were pretty screamy.
Oh, wait...that never happened. Sorry, my memory got jumbled.
There was that one time, however, when a small group of friends and I went spelunking, in the Appalachians. Those dames got pretty screamy when the mutant cave-people started chasing us.
Oh, wait..that also never happened.
Let's see, there was that time a group of terrorists robbed the building I worked in, on Christmas Eve, oh no, that never happened. There was that time a giant shark terrorized the tourist town I was, oh, no, that never happened.
Gosh, come to think of it, I've never been in a situation that is even slightly similar to the madness that happens in pretty much every movie. I guess I just don't know how I or anyone else would react. Maybe that's why they call it "fiction".
