Harry Potter lived at No. 4 Privet Drive with his aunt and uncle. He was locked up by Vernon, without food after he had broken plate which slipped from his tiny hands while washing and drying them, in his bedroom, which happened to be a broom cupboard under the stairs. He had also not been fed earlier that day by Petunia as he had failed to clean the garden. He was locked up even the next 2 days without being given anything to eat or even water. Only time he was allowed out was to use the washroom. This was a common occurrence at No. 4 Privet Drive, that Harry was blamed and starved for anything that went wrong. However, Venon usually will not hit him physically, except when he was too angry to control his temper when he had broken a rib or a bone in boy's little body. He had also never stopped a whale of his son to do so either. In last 4 years Harry had a broken arm, couple of ribs and a broken ankle. Each time he had been in his cupboard to heal himself.
Dursley's had told him that his father was a useless drunkard and that his parents had died in a car accident and he had somehow survived with that scar on his forehead. Dursleys had many time expressed their contempt that his parents had died and he was dumped at their doorstep.
Unknown to his relatives Harry had a photographic memory with total recall also called as Eidetic memory where the mind remembers everything read, heard or even smell and sensations perfectly with complete recall at will. Also, while Dursleys were against anything abnormal, Harry was anything but a normal child. He was a wizard and his parents had actually died at hands of a dark wizard who called himself Lord Voldemort. They had willingly sacrificed themselves to save Harry from Voldemort. And when Voldemort had tried to kill Harry the killing curse which had always killed had rebounded on the caster and Voldemort's body was destroyed. Unknown to anyone Voldemort had gone too far into dark arts and had created multiple Horcruxes to make himself immortal. When his body was destroyed (which never happens with a killing curse) his soul remaining in the body latched itself to only alive thing at that time and Harry had survived and was left with a unique lightening shaped scar at his forehead. Neither Harry nor Dursleys were aware that Harry and his scar were famous in Wizarding world and he was known as Boy-Who-Lived and was a celebrity.
Due to lack of food and water Harry was feeling very weak and was unable to even move. He felt that he will die due to lack of water or food in his already malnourished body. He was lying on his back on that excuse of mattress, that Vernon had thrown in the Cupboard for him to sleep on when, and he desperately tried to stay awake, but his body had little energy left and darkness claimed him.
His last memories and thoughts of his parents which came forward as the mind started to close towards oncoming death. He could remember and feel the love of his father who he had called Da, and for his mum who had sacrificed herself by taking the killing curse meant for him. His soul was filled with the immense love he had felt from his parents and also his godfather who he called "Siri". Also he remembered another face who he used to call "Mooye".
If anyone would have been able to see inside the cupboard they would find that young Harry's body was lifted almost to the ceiling of the cupboard and was encased within a blinding white light. Also within that white light filled with all the love was a black aura represented by Dark Lord's soul was right now fighting for its survival and tried to envelop the white aura. However his mother's selfless sacrificed which had saved him from the killing curse worked its magic again and the black aura started to shrink and with a loud shriek was completely disintegrated. If one was to check right now Harry's scar was now barely visible.
The shrieking noise had rattled No. 4 and entire neighborhood and the Dursleys came down angrily from their bedroom. Vernon had decided that he will give the boy a good beating for creating such ruckus that he will remember for his life. But when he reached the living room. Harry was still floating in the air and was surrounded by a blinding white aura that was now flaring further. As if paralyzed the Dursley's silently watch the aura receding into the boy's body who no longer looked weak or malnourished. As the aura finally with a pull fully receded into Harry his body gracefully landed to the living room floor. Had the Headmaster of Hogwarts been in his office at the moment, he would have noticed that one of his silver trinkets had stopped working and had completely melt down into a blob.
