Teach me to drive, Mum?

Me~ Ok Merlin, well this pedal here is the accelerator, makes you go faster.

Merlin ~ I like that! ok, what does this one do?

Me ~ that's the brake! it slows you down.

Merlin ~ what! What would I want to do that for? The other cars will catch up and steal my ball!

Me ~ I don't think you are ready for driving yet lad, shall we play ball instead?

Merlin ~ woof woof woof woof woof!
