Unpublished? Offer constructive feedback
This. I’ve read various friends’ manuscripts. Before accepting, you must know their intentions- are they looking for constructive criticism, or a pat on the back? My friends have specifically wanted criticism/feedback. I tried to balance it with compliments, but most people do not write well and don’t have a cohesive readable story. It takes drafts and drafts to get something polished. You could say “I love where you’re going with this, what an unusual/fascinating/hilarious/devious/thrilling story. I’m so impressed. Are you looking for feedback, I can share mine, if so!”
