Well, I finished critiquing my friend's novel. There were many pages. I tried to say "You might want to do this" as opposed to "You should do this," and I think I explained almost everything I said so that there were no random dicta. On the whole it still felt pretty negative though, and my friend hasn't gotten back to me yet. Hopefully he won't stop talking to me over this. Or even better, I hope he actually got something useful out of it.
