She stared at Tiffany's hopeful face and sighed.
"Come outside then," she said. "I'll give you lesson one. It's the only lesson there is. It don't need writing down in no book with eyes on it."
She led the way to the well in her back garden, looked around on the ground
and picked up a stick.
"Magic wand," she said. "See?" A green flame leaped out of it, making Tiffany jump. "Now you try."
It didn't work for Tiffany, no matter how much she shook it.
"Of course not," said Granny. "It's a stick. Now, maybe I made a flame come out of it, or maybe I made you think one did. That doesn't matter. It was me is what
I'm sayin', not the stick. Get your mind right and you can make a stick
your magic wand and the sky your hat and a puddle your magic...your magic...er,
what're them fancy cups called?"
"Goblet," said Tiffany.
