Q: Am I wrong to think that the book is less about either Will Grayson and more about Tiny Cooper?
Not really. I’ve always been interested in what happens when you give the narrative voice to the sidekick. In a way, WGWG is a novel in which two sidekicks are given narrative voices. (You don’t have to read it that way, of course, but I think you could certainly make the case that Tiny Cooper is the protagonist of the novel.)
