Whose Hellos Are These, Anyway?

In a not-so-ordinary mundane town, every greeting and salutation is inexplicably going missing. As an underappreciated postman, you embark on a quirky adventure through the eccentric neighborhoods of Quirkytown, where every resident has their own theory on where the greetings have gone. Engage in interactive dialogues, gather clues from the townsfolk, and confront bizarre situations that range from a Yodeling Yoga cult to a secret society of overly polite cats. Your task is to piece together the mystery of the vanishing hellos while ensuring that your own greetings don't land you in awkward situations. Will you restore the town's greetings or unwittingly create chaos?
