I never used 'uchi' anyway. It seemed odd having a Japanese term among English terms. I've never had to refer to them except in a post recently where I called them "sisterly" since that's what I saw on a Wiki.
I’m probably mostly alone in this—and it would definitely be hard to adjust to a new name now!—but I kinda wish they’d renamed Normals. Maybe into sweet or kind?
(What does “normal” even mean? Sounds boring and generic at best, and borderline offense to the other non-normal personalities haha)
Not sure if this has been posted, but I have just received my Animal Crossing New Horizons Official companion guide and it lists a bunch of stuff. One of those things is what reactions can be learned from certain villager types. Personality Sweet (??) - Pleased, Fearful, Sadness, Glee...
