"I!” said Aragog, clicking angrily. “I was not born in the castle. I come from a distant land. A traveler gave me to Hagrid when I was an egg. Hagrid was only a boy, but he cared for me, hidden in a cupboard in the castle, feeding me on scraps from the table. Hagrid is my good friend, and a good man."
