The Bomber has got a debit card now he's twelve. The initial idea being that he can take over responsibility for his online accounts (World of Warcraft and XBox Live Gold) and decide whether they are worth the dent they make in his pocket money.
Given that I pay them at the moment, the Burglar thinks this means I am taking money away from Ben, while presenting the change as a rite of passage birthday present. How true! I should have been a merchant banker. I can't see any flaw in the scheme at all.
