Alyx Stone wandered into the "Ollivander's Wand Shop" from Diagon Alley, following the instructions on her letter from Hogwarts. The 11-year old simply stepped into the shop and immediately a magical measuring tape flew over to her and began measuring her.

It whizzed around her taking her measurements and she spun around while she heard a voice, "Hold still, Alyx." It must have been the magical measuring tape because Alyx didn't see anyone working in the shop in front of her or behind the shop counter.

Alyx stood still taking it all in, excited to receive her first wand. She held up her arms as the measuring tape took the measurements and then she put them back down. A lot of the process seemed planned, as if the measuring tape behaved the same way for everyone buying a wand. After the measuring tape was finished and flew back over to the place where it rested on the shop counter, she waited for a few seconds and then said, "Hello? Is anyone there? I'm trying to buy a wand so I can go to Hogwarts!"
