"At school, Harry had no one. Everybody knew that Dudley's gang hated that odd Harry Potter in his baggy old clothes and broken glasses, and nobody liked to disagree with Dudley's gang."
Harry attended St. Gregory's Primary School, a Muggle primary school, with Dudley. He had no friends there, since all the students were afraid of Dudley's gang, all of whose members hated Harry because Dudley did. In particular, Dudley's friends liked to play a unique game — 'Harry Hunting' —(Harry Hunting was a bullying game which was created and played by Dudley Dursley and his gang. In the summer of 1991, Harry Potter had a rough time since Dudley's friends: Piers Polkiss, Malcolm, Dennis, and Gordon were coming over to his house every day) which involved chasing Harry. Although he was good at sports, he was always the last picked for a team because no one wanted to admit to Dudley that they liked him, rather than because he was no good.
Harry got decent, if not good grades at school. On one occasion, Harry accidentally turned his teacher's wig blue; on another, he accidentally apparated (magical way of transportation) onto the school kitchen roof when escaping from Dudley's gang; and on a third, he made Dudley's old jumper shrink as Aunt Petunia tried to shove it over his head. These incidents always enraged the Dursleys, and after each, they would punish Harry by throwing him into the cupboard — except for after the jumper incident because Aunt Petunia thought that the jumper had shrunk in the wash.
If Harry had not gone to Hogwarts, then he would have attended Stonewall High, a Muggle secondary school that Harry dreaded attending.
On 23 June 1991, Dudley's eleventh birthday, the Dursleys went to the zoo with Dudley's best friend Piers Polkiss. Unfortunately for the Dursleys, they had to take Harry with them, as Mrs Figg had broken her leg and Petunia's friend just had a boy so, there was no one to take Harry, and they refused to leave him alone in their house. At the zoo, Harry spoke with a boa constrictor and unintentionally made the glass of its enclosure disappear. This allowed the snake to slither out of his cage which scared Dudley into thinking it was after him. Harry was able to communicate in Parseltongue ( As a part of Lord Voldemort was in harry and parseltongue is the language of snake) with the freed boa, which thanked Harry briefly, then slithered out of the reptile house calmly. After this incident, the enraged Dursleys sentenced Harry to his cupboard until the beginning of the summer holidays.
