say what?

The other day a woman came into the knit shop with a quest. She had a lovely, lacy shawl that her sister had made 50 years ago after their aunt showed her how to knit. This woman had spent countless hours poring over knit pattern books trying to find the pattern so that she could make another. She had taken it to her knit group and everyone had studied it, but couldn't decipher the pattern. Could I help her?
I took the shawl and studied the pattern -- loopy and airy, it looked something like knit, but not quite.
"This is crochet," I told her.
No, no, it's knitted, she insisted. Her sister knitted it.
I selected a ball of yarn similar in weight to the shawl, then found a crochet hook. I began duplicating the pattern.
Another woman who works in the shop came over to study the shawl. "Oh, that's knitted," she said.
"It is knitted," the woman said. "She thinks it's crocheted."
They both looked at me. I held out my crocheted swatch.
They stared, mouths open.
"That's it!" said my fellow shop worker.
"Hmmm," said the shawl woman. She took the swatch and studied it.
"I studied books and books of patterns," she said. "I couldn't find it. My sister said she knitted it."
She was seeking an answer, and she found it.
It just wasn't the answer she expected.
