It is pretty powerful to hear something like that about something that you wrote. Of course I am pretty sure that my story just happened to be in the right place at the right time, but it was still so gratifying to hear.
Most recently, we used a writing prompt that one of the participants, a former teacher, used to unleash upon his class. For ten minutes we scribbled madly, expanding upon the opening line: "I am the one who ..."
I am the one who walks along these streets at night. When you are gathered with your family watching a late movie, I am passing your house. When you are gazing at the screen in your hand, ignoring the pile of books beside you, I am slowing down to get a closer look. When you are holding court in a room full of well-dressed beautiful people who sip fizzy drinks and nibble canapés, I am stopping on your sidewalk, half-hidden by your well-groomed trees.
I am the one who fights the urge to make my way up your sidewalk, to turn the handle of your door, to confront you. A startled you, who does not know that I only want to tell you that you would be much happier if you moved your couch over there.
