I think the lazies are early twenties with very childish personalities. Jocks are also early twenties. Smugs are late twenties, Snooties are late to early 30s, Crankies are late 30s to 40s, Peppies are early 20s, Uchis are late twenties, and Normals are also late 20s. I refuse to believe any of the villagers are younger than their 20s lol... although most of them are seriously irresponsible and should be dead by now with the way they furnish their homes and live their lives lmao. I imagine the residents in my town to be in their mid 20s, save for one, who I imagine to be a kid who still lives with her mom (who is never around).
