"You miss him!" Hermione said impatiently. "And I know he misses you —”
“Miss him?" said Harry. "I don’t miss him….”

"The Sorting Hat was sewn roughly one thousand years ago and was merely a normal hat belonging to Godric Gryffindor. When Gryffindor, along with Salazar Slytherin, Rowena Ravenclaw and Helga Hufflepuff, wondered how they would continue to sort the students when the four were dead, Gryffindor pulled his hat off of his head and, with the other founders, enchanted it with brains and some amount of personality. The Sorting Hat, now animated, was able to Sort and divide the students into the Hogwarts Houses, and continued to do so for a millennium, being owned by each Headmaster and Headmistress."
