" I thought I'd be seeing you soon. Harry Potter." It wasn't a question. "You have your mother's eyes. It seems only yesterday she was in here herself, buying her first wand. Ten and a quarter inches long, swishy, made of willow. Nice wand for charm work."
Mr. Ollivander moved closer to Harry. Harry wished he would blink. Those silvery eyes were a bit creepy.
"Your father, on the other hand, favored a mahogany wand. Eleven inches. Pliable. A little more power and excellent for transfiguration. Well, I say your father favored it- it's really the wand that chooses the wizard, of course. "
