YOU’RE reading a book, which is good and you are deservedly congratulating yourself.
Mostly As: Well done! You are reading a proper book, the kind that gets reviewed in Sunday papers. Make sure to mention it to everyone you meet or there will be no point.
Mostly Bs: You are reading a silly made-up book full of nonsense, like an IT worker would read. You have shamed yourself and your family.
Mostly Cs: You are reading a crime novel with a returning lead character that will be made into an ITV series as soon as a big-name actor gets desperate enough. You’ve wasted your time.
