In an older town, I had a villager like that named Rasher. I could not stand him at all, and at first, I kept ignoring him or whacking him with my net in hopes of getting him moved out. But I always felt bad about it...
Curiously, as time went on, I noticed him pinging me to give me items, quickly using the quotes of other villagers, and wearing cute clothing. It was as if he was adapting to his cringeworthy features, and it made me pity him even more. Then I decided to treat him nicer... Then he finally pinged to move out a month into my town!
