Words alone are not what one is used to during the conveyance of ideas in conversation. They are backed by tone, motion and expression. Surprisingly the effect of misinterpretation is positive. Perceived ideas are easily moulded into what the reader wants to visualise rather than have someone else's views imposed on oneself as a result of a rebuttal. Perception is key here.
Any idea conveyed in any manner is unimportant, the manner in which it is finally received is key.
A written account is only accurate at the time of writing and even then only to the author at that time. A story must have a twist. The biggest killer of original free flowing thought by far. An author is pressured to twist his tale to end it with a twist. Too many a tale could do without an easily caught drift from the theme at the very end, a concealed attempt to allow for a twist.
