They don't hear what we withhold, because they can't read minds. They only have the part of us we share with them; they don't do as much "imagining" as we do about what we're going to say, what we're feeling, who's on first :-)

Our story is just ours, the theme may be similar to others but the details aren't the same; think of all the books you've read with the same plot but remember how very different they are! They're excited to be reading the book of you but can only go as fast as you turn the pages, there's no way to skip ahead.
