For me, one of the reasons I love this form - the personal essay form - is because it's a way of forming an intimacy with the reader. What I'm saying to the reader is: I'm going to tell you something; I'm going to be generous; I'm going to offer. The confession, on the other hand, is sort of an imposition because you're asking the reader to forgive you or somehow exonerate you or say, "Hey, I'm even worse." But what I'm interested in doing is being generous and offering a perspective or suggesting a way of thinking about something.
