Keep in mind that Augusten himself acknowledges in some of his other books that he can be an unreliable narrator- in his memoir Dry there are certainly remembered experiences that likely did not happen in the way he recalls, but that’s kind of the point, IMO. These are his experiences dealing with trauma, getting sober…A Wolf at the Table, which deals more with his childhood prior to Running With Scissors, is probably something you would be interested in reading.
