A co-worker of mine asked me to read his novel to see if I want to edit it. He wants it polished before he self-publishes through Amazon. I just finished reading it yesterday and... I've extremely little positive to say about it. I intend on being honest with him, as gently as I can, but there are some potential complications involved. Based on what I've read and some of the things I've heard him say, I think he's sexist. He has 20-30 years on me and seems to put high value in age. He's often emphasized that if this isn't my "thing," that's okay and I don't have to worry about editing his work (notably, he said that in response to me pointing out how cliché a character was). He's arrogant and thinks he's clever, but I see no basis for these beliefs in his writing. He clearly wants to write and takes it seriously, but I'm afraid he's not going to take me or anything I say seriously. He needs the help, and I think I can help him if he'll listen. I don't think he's ever received serious feedback on his writing before. I was in his shoes 10 years ago... Has anyone else experienced such a situation in critiquing or editing? Does anyone have advice for tackling this?
