How many villagers have you adopted from the same town - perhaps from a cycle town or a sibling's town? I have 3 villagers in my main town who came via my second/cycle town. Why don't these villagers remember each other or realize they are from the same town? It would be so fun to hear a conversation between them about their old town or have them strike up the old town tune together. I can just hear them gossiping about their old mayor together.
