Incomplete Thoughts

Is there such a thing as a complete thought? When, as writers, do we know our meaning has been entirely understood by our reader?  Is it possible to have entire understanding between two people? After all, there are only so many human experiences, just as there are a limited number of stories, written over and over again from different perspectives. But still, I think not.

It occurred to me that writing a thought is like taking a step. No matter how many times you think you’ve taken your last step, come to the end of your journey, there will always be another step to take until you die. Then all there is left is for someone else to attempt to interpret your life, your steps, your thoughts.
