"Why, we're delighted to have you, Frank," she assured him.
Bob, who had been looking out of the window all this time, turned abruptly.
"Mother, Polly doesn't want any tea, and there's loads of time for a walk; do you mind?" he asked.
His mother laughed. "Not if Polly doesn't, but I should think she'd be tired."
But Polly was not tired. She insisted that she wanted some exercise after the trip on the cars. So Bob took her out.
The sun was just getting ready to set, and they walked towards the river.
"Polly!" Bob said, after they had walked a block in silence.
"Yes—"
"I think this is pretty much O. K., don't you?"
"What, this street?" Polly was very happy and she felt like teasing.
