Sammy was busy playing on the computer.  Desperately enjoying the last day of term break (he doesn't know there's one more week of vacation left). 

He had just finished doing the Gauss Year 7 exam and Daddy wants to review his mistakes.

Daddy: Sammy, come on, let's review your mistakes.

Sammy:  (hard at play on the computer) Daddy, please, you know better than that...
