The third encounter came towards the end of the afternoon when Sophie had worked her way quite high into the hills. A countryman came whistling down the lane towards her. A shepherd, Sophie thought, going home after seeing to his sheep. He was a well set up young fellow of forty or so. "Gracious!" Sophie said to herself. "This morning I'd have seen him as an old man. How one's point of view does alter!"
When the shepherd saw Sophie mumbling to herself, he moved rather carefully over to the other side of the lane and called out with great heartiness, "Good evening to you, Mother! Where are you off to?"
"Mother?" said Sophie. "I'm not your mother, young man!"
"A manner of speaking," the shepherd said, edging along against the opposite hedge. "I was only meaning a polite inquiry, seeing you walking into the hills at the end of the day. You won't get down into Upper Folding before nightfall, will you?"
Sophie had not considered this. She stood in the road and thought about it. "It doesn't matter really," she said, half to herself. "You can't be fussy when you're off to seek your fortune."
"Can't you indeed, Mother?" said the shepherd. He had now edged himself downhill of Sophie and seemed to feel better for it. "Then I wish you luck, Mother, provided your fortune don't have nothing to do with charming folks' cattle." And he took off down the road in great strides, almost running, but not quite.
Sophie stared after him indignantly. "He thought I was a witch!" she said to her stick. She had half a mind to scare the shepherd by shouting nasty things after him, but that seemed a little unkind.
