“Seventeen, eh!" said Hagrid as he accepted a bucket-sized glass of wine from Fred.
"Six years to the day we met, Harry, d’yeh remember it?"
"Vaguely," said Harry, grinning up at him. "Didn’t you smash down the front door, give Dudley a pig’s tail, and tell me I was a wizard?"
"I forge’ the details," Hagrid chortled.”
