A teacher seeing the inattentiveness of a student in the course of the lesson might interrupt the lesson to tell him: Listen to me carefully, and then resume his speech, This sentence will certainly seem to be irrelevant to those who might be unaware of the incident and might read the lesson when it is printed and published word for word, But the one who is aware of the incident because of which this sentence was interposed, will feel satisfied that the lesson has been reproduced verbatim and nothing has been increased or decreased in it in the process of reproduction.
