Harry James Potter sat in his bedroom at number four, Privet Drive. It was a hot summers day, and his window was open. He was packing his suitcase in the hope that the Dursleys would throw him out, therefore giving him a reason to run far away, far enough for Minerva McGonagall and all of her minions at Hogwarts to lose track of him at least.
During the term prior to that day, Harry had discovered that his mortal enemy, Lord Voldemort, had hidden pieces of his soul in objects called Horcruxes, making him almost immortal. After that, Harry had decided to make it his job to find and subsequently destroy these items of dangerous power.
Harry looked out of his window at his Aunt Petunia pruning the garden hedge. She was doing it awfully slowly for a woman who managed to beautify the whole of her humble yet pretty back yard in just a few hours. He blinked. His long-necked auntie was standing more than three metres away from where she was a split-second ago, the hedgerow between where she was and where she had been was just as carefully trimmed as the rest of the leafy fence that she'd been at all morning.
Harry then watched as she stepped backwards and looked around. Luckily she didn't look up, or she would have seen him staring at her confusedly, wondering what she was doing. What Petunia Dursley (neé Evans) did next was so astounding to Harry, he never quite recovered from the shock he was in. His self-conscious aunt then brandished a long thin piece of wood and Harry scrutinized bemusedly as she uttered a couple of indistinguishable syllables and tapped the hedge twice with her little cane. As she placed the stick back in the pocket of her skirt, Petunia happened to glance upwards and see her nephew staring at her, his eyes wide with befuddlement.
She placed her hand over her heavily lipsticked mouth and sighed. She beckoned Harry towards her, and he followed, as if in a trance.
