Kid's Excuses to get what he wanted

Dad woke his 7 y.o. kid up,

7 y.o. :"Dad, I'm really tired, can't I sleep in the car?!"
Dad :"Nope, But you can walk back to rest in your bedroom."

The kid got out from the car reluctantly and while walking back home with his dad,

7 y.o. :"Dad, I am tired, but you wake me up, so, can I play computer games?"
Dad :"Not until you complete your homework."

7 y.o. :"Dad, I can only play computer games now..."
Dad :"WHY?!"

7 y.o. :"Because I will need more energy to hold the pencil and write when I do my homework ..."

7 y.o. :"... But I only need one finger (press the keyboard) to play the computer games."

7 y.o.:"... I won't play games that need the mouse."
