"Yes! I want it! And I'll wait for him."

"If your mother can pay for the wand, I'll accept that for a brief lesson."

Payment: happens.

Sadde: watches.

"Very well. Enjoy the wand, boy. Now, for your lesson. Wood and core reflect a wizard's character, augmenting it. Some wands seek wizards to balance, while others seek witches that match. Wand length is often based on the size of a wielder's personality, and flexibility represents their flexibility, if you will. Take your wand. Smaller than average, but not unusually so. You are more restrained in your expression of your core traits- but as we take a look at the wood and the core, we'll see your flashy tendencies are reflected elsewhere."

"Huh. So... Scott should probably get something nice and kind that likes helping others, from what I've seen?"

"I'm sure that's right, though I don't know the boy at all. I typically get a sense by offering a more friendly, adaptable wand first, to see why it doesn't fit, if it doesn't, and move on to a more suitable fit." 

Pear, unicorn hair, slightly bendy?

Nope. 

"Don't people change a lot in their teens, though?"

"Some will find new wands as they get older, if not wiser. Most pairs, however, will grow together. The wand chooses the wizard." 

"—are wands sapient, too?"

"I'm not quite sure what you mean."

Cedar, dragon heartstring, eleven inches...

It gives off a few sparks, which Scott seems pleased by, but Ollivander shakes his head and retrieves another one.

"Are wands people? Do they have memories, personalities, thoughts, preferences?"

"I can't say I've ever wondered if wands had memories, but they do have temperaments and preferences. They may be no more complex than Crups or Granians, but they are unique."

"What are Crups and Granians?"

"Crups are creatures which are very loyal to their owners. They bark in the presence of Muggles. Granians are a breed of winged horse."

Ollivander hands Scott another box ("10 1/2 inches, oak").

He waves the wand, and there's a swirl of cool air as the tip glows warmly.

"So cool."

"Oh. Makes sense, I guess." He looks at Scott and beams. "Wands are cool!"

"If that's all, you can both be on your way." 

He nods. "What's your core, anyway?" he asks Scott.

"English oak, unicorn hair, supple, ten and a half inches," he recites. 

"I still don't understand how they can like different wizards and not be people." 

"Mr. Ollivander is very interested in wands, so he probably thinks of them that way, even though they're not." 

"And dogs like people but are not themselves people," she points out, "so even if wands are sentient they're not necessarily also sapient."

"But how do we know wands are more like dogs than humans? And we don't let people be mean to their dogs, what if they're mean to their wands?"
