Dudley began to cry loudly. In fact, he wasn't really crying — it had been years since he'd really cried — but he knew that if he screwed up his face and wailed, his mother would give him anything he wanted.

      "Dinky Duddydums, don't cry, Mummy won't let him spoil your special day!" she cried, flinging her arms around him.

      "I... don't... want... him... t-t-to come!" Dudley yelled between huge, pretend sobs. “He always sp-spoils everything!” He shot Harry a nasty grin through the gap in his mother's arms.

      Just then, the doorbell rang — "Oh, good Lord, they're here!" said Aunt Petunia frantically — and a moment later, Dudley's best friend, Piers Polkiss, walked in with his mother. Piers was a scrawny boy with a face like a rat. He was usually the one who held people's arms behind their backs while Dudley hit them. Dudley stopped pretending to cry at once.

      Half an hour later, Harry, who couldn't believe his luck, was sitting in the back of the Dursleys' car with Piers and Dudley, on the way to the zoo for the first time in his life. His aunt and uncle hadn't been able to think of anything else to do with him, but before they'd left, Uncle Vernon had taken Harry aside.

      "I'm warning you," he had said, putting his large purple face right up close to Harry's, "I'm warning you now, boy — any funny business, anything at all — and you'll be in that cupboard from now until Christmas."

      "I'm not going to do anything," said Harry, "honestly..."

      But Uncle Vernon didn't believe him. No one ever did.

      The problem was, strange things often happened around Harry and it was just no good telling the Dursleys he didn't make them happen.

      Once, Aunt Petunia, tired of Harry coming back from the barbers looking as though he hadn't been at all, had taken a pair of kitchen scissors and cut his hair so short he was almost bald except for his bangs, which she left "to hide that horrible scar." Dudley had laughed himself silly at Harry, who spent a sleepless night imagining school the next day, where he was already laughed at for his baggy clothes and taped glasses. Next morning, however, he had gotten up to find his hair exactly as it had been before Aunt Petunia had sheared it off. He had been given a week in his cupboard for this, even though he had tried to explain that he couldn't explain how it had grown back so quickly.

      Another time, Aunt Petunia had been trying to force him into a revolting old sweater of Dudley's (brown with orange puff balls). The harder she tried to pull it over his head, the smaller it seemed to become, until finally it might have fitted a hand puppet, but certainly wouldn't fit Harry. Aunt Petunia had decided it must have shrunk in the wash and, to his great relief, Harry wasn't punished.

      On the other hand, he'd gotten into terrible trouble for being found on the roof of the school kitchens. Dudley's gang had been chasing him as usual when, as much to Harry's surprise as anyone else's, there he was sitting on the chimney. The Dursleys had received a very angry letter from Harry's headmistress telling them Harry had been climbing school buildings. But all he'd tried to do (as he shouted at Uncle Vernon through the locked door of his cupboard) was jump behind the big trash cans outside the kitchen doors. Harry supposed that the wind must have caught him in mid-jump.

      But today, nothing was going to go wrong. It was even worth being with Dudley and Piers to be spending the day somewhere that wasn't school, his cupboard, or Mrs. Figg's cabbage-smelling living room.
