How do you end a story that’s not yours? Add another sentence where there is a pause? Infiltrate the story with a comma when really there should have been a period? Punctuate with an exclamation point where a period would have sufficed? What if you kill something breathing and breathe life into something the author wanted to eliminate? How do you get inside the mind of a person who isn’t there? Fill the shoes of someone who will never again fill his own?
