Have you ever taken an ordinary broomstick and expected it to fly?
Do you go to school and wonder where the Transfiguration department is?
Have you ever injured yourself by running into the wall between Platforms 9 and 10?
Do you ever pick up random sticks from the gutter, wave it around and expect something to happen?
If you've answered yes any of the questions above, I congratulate you for being a superb Harry Potter fanatic!
