This seems obvious but is actually something most people miss as they assume because they see the narative and all of the little hidden gems, everyone will see the same thing. Many writers here try to convey what is in their head which is great but, they do it from their perspective and lose the audience. They of course wonder why their masterpiece is not well received. It is kind of like telling the punchline of a long joke and expecting the audience to laugh without having heard the rest.

This is very relevant in something as mundane as giving directions as well. To be able to give clear and unambiguous directions one needs to model the level of knowledge the recipient is likely to have. This is often a cognitive task far from trivial which most people fail at to one degree or another in my experience. It is often frustrating to ask a local for directions in some strange city because one can almost expect them to fail to not only grasp the ambiguities of the expressions they use but neglect to mention things someone totally new to the area must be told before they can make any use of the information.
