I remember Pompom wanted to move away, but then she changed her mind suddenly. And the next day, I got a letter from her saying that I was her best friend ever and that she hopes to stay friends with me. :')
Everyday, I receive letters from one of my villagers (the one who sends it changes everyday) where they usually tell me that they appreciate me. They're SO cute!
I have a trove of letters I've saved at the post office!
Who know letters sent to you by a fictional, pixelated creature can have such a nice, endearing effect on you! Just one of the many reasons why I love this game!
