The good thing about not having a girlfriend is that you don't have to watch the Twilight movies, lol. A lot of my friends have suffered this fate. But unless you're into a romance featuring partially nude emo kids with extraordinarily bad acting, you won't like this.
I must say I am very surprised that there are people who haven't heard of this, even if they aren't fans. It's like not knowing what a Playstation or text messaging is.
