From the writer's point of view, critics should be ignored, although it's hard not to do what they suggest. I think it's unfortunate to have critics for friends. Suppose you write something that stinks, what are they going to say in a review? Say it stinks? So if they're honest, they do, and if you were friends you're still friends, but the knowledge of your lousy writing and their articulate admission of it will be always something between the two of you, like the knowledge between a man and his wife of some shady adultery.
