'Oh, much better!' cried the Queen, her voice rising to a squeak as she went on. 'Much be-etter! Be-etter! Be-e-e-etter! Be-e-ehh!' The last word ended in a long bleat, so like a sheep that Alice quite started.
She looked at the Queen, who seemed to have suddenly wrapped herself up in wool. Alice rubbed her eyes, and looked again. She couldn't make out what had happened at all. Was she in a shop? And was that really—was it really a SHEEP that was sitting on the other side of the counter? Rub as she could, she could make nothing more of it: she was in a little dark shop, leaning with her elbows on the counter, and opposite to her was an old Sheep, sitting in an arm-chair knitting, and every now and then leaving off to look at her through a great pair of spectacles.
'What is it you want to buy?' the Sheep said at last, looking up for a moment from her knitting.
