Proving a Point

In doing the Close Readings of First They Killed My Father I realize all of the things we inevitably miss when reading something for the first time. How frustrating it must be for the writer, knowing his or her book will only be skimmed and even if it is read thoroughly the fullest meaning will not be understood. A large portion of the time we interpret symbolism and rhetorical devices in a way that the author did not intend. If writers' merits are measured based on how effectively they prove their points, we can never accurately judge the their skills without being 100% sure of their intentions. So instead we judge how well they prove a point but what if the author was trying to prove the opposite. Seems unlikely but when an argument gets complicated enough like in "The Sweet Smell of Success" miscommunication is entirely possible.
