No matter how hard you try, you reader won’t get all the ideas, plot, and intentions that you put into your story.
This can be dangerous. It can make you question whether you planted the information correctly and make you telegraph your intentions. It’s a balance of trusting the intelligence of your reader and being trustworthy enough to gently guide him along.
No reader operates as closely to the work as you write. It doesn’t mean that you shouldn’t do the work, but that you shouldn’t get upset that they didn’t find it all.
