"The key to making anything come to you is in how badly you want it," Bianca told her. "Let's start with something smaller." She went to the kitchen and retrieved a bar of chocolate. She brought it back and laid it on an end table about halfway across the room.
"That'll do," Fenrir said, sure that Liza probably liked chocolate. Most kids did. "Now, stand up. Concentrate on the chocolate and how good it will taste when you get it. Focus on how badly you want it. Then, when you're ready, point your wand at it, and accio the chocolate to you. Give it a try."
Fenrir figured the school had a reason for only teaching theory, but, hell, by his third year, Potter had already found the sorcerer's stone, defeated a mountain troll, killed a basilisk, skirmished with Voldemort a couple of times...and Liza couldn't accio her wand. Shameful humans. Greybacks were of better stuff than that. He really didn't give a jot for Ministry law or rules. Nor did he particularly give a jot about LIza's neurotic and demanding mother. He did feel rather committed that his offspring be able to not only protect themselves but be sufficiently able to deal it out if it came to it. The child in front of him was immature and entirely too naieve for her age, and far too much for her own good and safety. And all the coddling her mother could give her would keep her safe. However, having some realistic thinking and a decent hand with a wand just might help the girl quite a lot.
