LOL! I know what you mean, but I've found that the snooty villagers actually warm up really quickly. Run a few errands, hand over fruit...and they become very sweet. I also like the conversation where they report gossip: "Rumor has it you're a bit of a bell-pincher. Well, I've certainly been called worse." That always cracks me up!
A friendly snooty villager is actually sweeter than a peppy villager in my experience. Anyway, Blaire became sweet as can be, and she is STILL up for adoption! Two people who have shown interest have not actually made pickup arrangements. I'm keeping my town on the same day indefinitely, and starting to feel like Bill Murray.
