Reality is not constructed in the same manner as movies or dramas, novels or manga. That's a disappointment to you, isn't it? The protagonists in the entertainment world, one day, suddenly, will find themselves faced with an unrealistic phenomenon, sense trouble, and will find themselves placed in a situation which could hardly be called pleasant. In the majority of cases, those stories' protagonists will, using intellect, bravery, a hidden power, or through developing an unspecified talent, overturn their broken-down circumstances. However, those are stories which undoubtedly can only occur in the fictional world. And it's because they are fiction that they are consequently realized in the entertainment world. If we were to posit that a world like in movies, dramas, novels, and manga was made to be ubiquitously visible in everyday life, then those forms of entertainment would not longer be entertainment, they would be documentaries.

David: Is this a game or is this real?
WOPR: What's the difference?
There's dozens of our men looking at the Death House right now because they got snitched off. Not infiltrated - those movies where they put undercovers in prison, never happen. Couldn't happen.

Dr Cox: Look, I know you all curl up on your futons at night dreaming of cracking a real-life medical mystery so that some Doctor-slash-supermodel will want to touch your eruption button, but here's the bad news. This isn't a TV show, there aren't any cameras over here, real medical mysteries don't happen every week and doctors damn sure don't look like models. They look like Rex.
Dr Cox: Chin up, you ugly bastard.
“So who's resetting those traps then?” Louise asked, more to herself.
She almost expected some hideous and reptilian voice to call out “I am,” but that only happened in cliched stories.
[Siesta's] life was not like ''A Country Maid in the Hall of the Duke''! This would end badly, no matter what those romance novels had said! She lived in reality, dammit!
"Halflings!" laughed the rider that stood beside Éomer. "Halflings! But they are only a little people in old songs and children's tales out of the North. Do we walk in legends or on the green earth in the daylight?"
Irving Lambert: Looks like there's an active alarm system...

My own pretty words aside, life is no play. We meet people once, and never see them again. There is no shape to events, no point at which we turn to the audience for praise. No time at which we step behind the stage, to see the actors changing their wigs, and painting their faces, and muttering their lines.
