Harry Potter and the Order of the Phoenix started out like every other Harry Potter book. Harry had to suffer at his aunt Petunia and his uncle Vernon's square house on Privet Drive during the summer. Petunia and Vernon Dursley were what you call "muggles". They were close-minded non-magical folk who despised all witches and wizards. That was the main reason why they treated Harry like he wasn't even a human being. He found out he was a wizard on his eleventh birthday and has went through a lot ever since. Along with his aunt and uncle, Harry had to deal with his bully cousin Dudley. Without the use of magic, he was pretty much defenceless against him. In addition to all that, he was just like any other teen boy. He started to lose his temper a lot more and all the things only Harry had to deal with was getting too much for him. .
An example of this is on page 63. "But before he knew it, Harry was shouting. "SO YOU HAVEN"T BEEN IN THE MEETINGS, BIG DEAL! YOU"VE STILL BEEN HERE, HAVEN"T YOU? YOU"VE STILL BEEN TOGETHER! ME, I"VE BEEN STUCK AT THE DURSLEYS" FOR A MONTH! AND I"VE HANDLED MORE THAN YOU TWO"VE EVER MANAGED AND DUMBLEDORE KNOWS IT - WHO SAVED THE PHILOSOPHER"S STONE? WHO GOT RID OF RIDDLE? WHO SAVED BOTH YOUR SKINS FROM THE DEMENTORS?" Then continued on page 64. "WHO HAD TO GET PAST THE DRAGONS AND SPHINXES AND EVERY OTHER FOUL THING LAST YEAR? WHO SAW HIM COME BACK? WHO HAD TO ESCAPE FROM HIM? ME!" "BUT WHY SHOULD I KNOW WHAT"S GOING ON? WHY SHOULD ANYONE BOTHER TO TELL ME WHAT"S BEEN HAPPENING?" " CAN"T"VE WANTED TO THAT MUCH, CAN YOU, OR YOU"D HAVE SENT ME AN OWL, BUT DUMBLEDORE MADE YOU SWARE. " FOUR WEEKS I"VE BEEN STUCK IN PRIVET DRIVE, NICKING PAPERS OUT OF BINS TO TRY AND FIND OUT WHAT"S BEEN GOING ON." "I SUPPOSE YOU"VE BEEN HAVING A REAL LAUGH, HAVEN"T YOU, ALL HOLED UP HERE TOGETHER.".
On a walk back from a park Harry went to, he met up with his cousin Dudley. On their way home, Dudley and Harry met up with some dementors.
