The Dursleys weren't the most successful family in the neighbourhood, but they were extremely sociable and mild-mannered. Having lived in Privet Drive for over a decade, everyone in the town knew their names. Vernon Dursley, the head of the household, was a man rather on the plump side, but he was jolly and enjoyed dressing up as Santa Claus during Christmastime to please the children. His wife, Petunia Dursley, was a rather shy, petite woman, but she still got along well with most people - and their son, Dudley, was the sweetest boy you'd ever see. He had many good friends in school, and he aspires to become a community worker when he grew up.
Everyone said good things about the Dursley family, except for their nephew. The Dursleys has been taking care of Harry James Potter since the day Lily and James Potter died in a car crash, and loved him just like their own son, but Harry didn't seem to take it that way. As Harry grew older, he became bitter and distant from everyone, even neglecting to eat and tried to convince others that the Dursleys have been starving him. Petunia, concerned about her nephew, was not particular about her reputation being falsely destroyed, and instead tried hard to reach out to him - yet her aid reached deaf ears.
As Harry grew, he began to engage in more and more criminal activities. For one, he has been climbing school buildings, overturning dustbins, and one time he even let out a boa constrictor in the zoo, and attempted to convince everyone that he was using the 'power of his mind' and his 'love for animals'. The Dursleys could not take it anymore. Tearfully, the decided that they had no choice... but to send Harry Potter to St. Brutus's School For Incurably Criminal Boys.
His conduct had not been well. He has been showing more and more delusional tendencies while in school - like calling it "Hogwarts" proudly and repeatedly, and singing "study until our brains all rot" during dinnertimes. Over and over again, Harry has been caught roaming school corridors at night, jabbing at the wallpaper with wooden sticks, yelling "Lumos" and other strange semblences of Latin words. To the teachers' worry, Harry Potter had even befriended the notorious school bully, Ronald G. Wesley, who also spurred Harry on with his delusions, and Herbert Granger, whom he kept treating like a girl.
Harry, Ronald and Herbert all appear to have deluded themselves into believing the existence of magic. They have also been exhibiting highly violent and destructive tendencies, especially to the volunteers from outside who have kind-heartedly applied to join the school are caretakers and teaching assistants. One such example is Draco Malfoy, who is usually found bruised and beaten up by Harry and his gang. Harry has taken a liking to jabbing him repeatedly with his wooden stick.
The staff believe that Harry was now posing a significant threat. Harry had even maimed a teacher by clubbing him in the back of his head after tearing off his turban, causing him to resign in fear. When question, Harry Potter repeatedly said that the Prime Minister was coming after him. Nobody had any idea why the distinguished and well-liked Prime Minister Tom Riddle would ever target a child, but clearly Harry Potter was out of his mind.
In the end, all the staff were at a loss on how to take care of this boy. He was clearly delusional, however, and had been sent to the a nearby mental institute to seek treatment.
