Corner

"The man stood in the corner."

And immediately your mind starts to actualize the text by contributing a sense of the man's age, size, skin colour, clothing, facial appearance and maybe even emotions. Your mind might even start to actualize the corner in question and the way he stood. This process of concretization allows a text to be read in a multitude of ways and probably evidences how reading a book stimulates the brain more than watching a movie of the same title. It is innately human to want to fill in the gaps, a man in the corner, snippets of a telephone conversation, a nervous twitch or a fleeting change of the conversation topic.
