Your neighbours are going away for the weekend – a romantic second honeymoon, so it happens – and have asked you to babysit their kids. Both boys, and being aged eight and 12, they are heavily into video games. When they arrive, they're brandishing a copy of Call of Duty: Modern Warfare 2. Their parents bought it for them, even though it's an 18-classification game. Your kids, of the same age, who you don't let play age-innapropriate games, are goggle-eyed and want to play it straight away. What do you do?
