It's either Love/Like/Hate or Like/Neutral/Dislike or some combination of those. Anyhow, I figured out neutral gifts and the rest of the loved gifts, most of them at least. Pics included because I've mixed up loved reactions with the neutral ones, especially Ember and Lyrus.
I missed Scout hating iron ore on my other post. Items I haven't tried: Lunar butterfly, tropical butterfly, black firefly, catfish.
