You write a letter, create some sort of document which must be sent to what seems like a hundred different people. Each person normally feels the need to put their fingerprint on it and change something just to say they did. Once it comes back to you the message has nothing to do with how you began.
That one little sentence you added will not likely make a damn bit of difference.
Maybe I'm too laissez-faire but I think if we let things be a little more often they would have room to improve on their own.
