I've never cared much for having one of each villager personality type, I've chosen my dreamies purely based on aesthetics. I've learned recently that different personalities give different reactions so now I may need to let some temporary residents come and go. Trying to decide if I also want to go for the reaction given to best friends only, since that will be more of a commitment. Can you share based on your own experiences how long it usually takes to reach that best friend status?
