It happens all the time. You write an email, letter, or even some sort of business document and think that everything is done but when you look it over again you realize that you missed something. Nothing that impacts the content as all of the information is there but there is a single seemingly insignificant dot or subtle line that has been either added or not included that completely changes how it is read.

"We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness.--That to secure these rights, Governments are instituted among Men, deriving their just powers from the consent of the governed, --That whenever any Form of Government becomes destructive of these ends, it is the Right of the People to alter or to abolish it, and to institute new Government, laying its foundation on such principles and organizing its powers in such form, as to them shall seem most likely to effect their Safety and Happiness."
