Chapter One
"Ready, are you?"
It was Uncle Vernon, still purple-faced, still mustached, still looking furious at the nerve of Harry, carrying an owl in a cage in a station full of ordinary people. Behind him stood Aunt Petunia and Dudley, looking terrified at the very sight of Harry.
"You must be Harry's family!" said Mrs. Weasley.
"In a manner of speaking," said Uncle Vernon. "Hurry up, boy, we haven't got all day." He walked away.
Harry hung back for a last word with Ron and Hermione.
"See you over the summer, then."
"Hope you have - er - a good holiday," said Hermione, looking uncertainly after Uncle Vernon, shocked that anyone could be so unpleasant.
"Oh, I will," said Harry, and they were surprised at the grin that was spreading over his face. "They don't know we aren't allowed to use magic at home. I'm going to have a lot of fun with Dudley this summer . . . "

Harry then proceeded to follow Uncle Vernon out of King's Cross toward the car, lugging his trunk the entire way.
Once he had packed his trunk into the car and squished himself into the backseat with Dudley they headed back toward Privet Drive. Harry thought this was just going to be another summer with the Dursleys, full of chores and little to no food, however he would soon discover it was not to be.
