Let Ai=[ai1,…,ain] be all properties of a house qi, and S the standard deviation. For any house qi from the collection of houses Q in a radius of 200m around 4 Privet Drive where i≠j, |[Ai - Aj]| S.

Harry's and Dudley's maternal grandmother was the same person.

Harry's eyes reflected most light with a wavelength of 512nm, Harry's hair reflected very little light. Dudley's eyes reflected most light with a wavelength of 492 nm, while his hair reflected most light with a wavelength of 581 nm. Dudley's BMI equalled 20.5, which put him in 99th percentile for BMI for his age, Harry's BMI was 9.3, which put him in the 1st percentile.

On Monday, 7th of April 1986, at 11:32:08, Dudley chose to vocalize "The hunt is on!" with a volume of 102 dB.

Harry's heart rate rose to 219 beats per minute. Harry's quadriceps, hamstrings, buttock muscles, stomach muscles and calf muscles activated.

Let the energy used by Harry during his run, Espent, be only the kinetic energy used to move around, Force times distance travelled, F*S=Espent, with an assumed efficiency of 100% for simplicity's sake. Let Efood be the amount of energy that Harry's body could obtain from his allotted meals. Then Espent Efood. Therefore Dudley's location and Harry's location were equal within 315 seconds.

Dudley's arm transferred its momentum to Harry. Since Marm and MHarry were in the same order of magnitude, and Varm was high in comparison to VHarry, Harry gained a lot of momentum in the inelastic collision.

Harry cried. Dudley laughed.

Translation:

All the houses around 4 Privet Drive were the same.

Harry is Dudley's cousin.

Harry's eyes are green, his hair black. Dudley's eyes are blue, his hair blond. Dudley was rather fat, while Harry was extremely thin.

Dudley screamed: "The hunt is on!" rather loudly.

Harry ran.

Since Harry was rather unfit due to malnourishment, Dudley easily caught up with Harry.

Dudley hit Harry rather hard, so Harry fell over.

Harry cried, Dudley laughed.

A/N:

Boo. I've managed to escape from the black hole of free time otherwise known as 'College Life' long enough to write this piece. I'm sorry for the unfortunately long delay in updating my other fics, but I can only offer empty promises. The first scheduled time off is in roughly 61 years, but I'll try and update it somewhere before 2074. Review please?

A/N: Edited. Changed 'impulse'(Dutch) to 'momentum'(English).
