Fun Game: Mafia

Introduction

Just a game to play when bored.
Okay, as I said in the description, this is a popular game amongst my friends, so I thought I'll share it with my fellow Wattpadders.
Basically preteen level, but any group of bored people can do it.
It's an indoor roleplay group activity, but it doesn't involve moving around. In fact, you need to sit in your chairs around a table.
We used to play it at school when a teacher was absent but we were made to stay inside the classroom.
