When Harry was still a little boy, all kinds of strange things were always happening around him.
For instance, Dudley's ugly old sweater. Aunt Petunia always forced Harry to pull it on, and the more she made him wear it, the smaller it became, until eventually it was small enough for only a doll to wear.
Every time he had his hair cut, it looked as though he had never had one. Eventually, Aunt Petunia could stand it no longer and cut Harry's hair herself with scissors, leaving only the tuft over his forehead to hide that lightning-shaped scar.
His classmates already mocked his perpetually baggy clothes. As he tossed and turned on the bed in his cupboard, wondering whether he should go to school the next day, he woke the following morning to find that all his hair had grown back.
There was another time when Harry was found on the school roof. Dudley and his gang had been chasing him, and in the blink of an eye, he found himself sitting atop a chimney.
He had been no less frightened than anyone else, but it was the adults who got angry.
"Don't play any tricks." Before they left for the zoo, Uncle Vernon warned him, "If anything goes wrong today, you won't get dinner for a week."
Harry solemnly promised that nothing would go wrong. Even at lunchtime in the zoo, when Dudley chased him, he did not run onto the roof of the restaurant like last time.
It was a bright, sunny weekend, and tourists were everywhere, out with their families or travelling. Everything looked perfectly normal until he reached the artificial hill where the lions were kept.
