He blinked and the city was gone. In its place was an empty, grassy field.

"How the hell am I supposed to find the dentist's office without any streets or buildings to guide me?" he thought.

"Oh, well," he shrugged and continued walking in the direction he had been going, down what had just been Broadway. After about a quarter mile, he turned right, thought about it, and turned a little more.

"Hope Street should be about here," he said to himself. "And the dentist is two blocks down."

He tore out some grass and made a little hole to mark the intersection for his return trip Then he fixed his gaze on a spot he estimated to be two blocks down Hope Street and walked towards it. When he reached his destination, he turned to face where the dentist's building would have been and reached out his finger to press the buzzer. Of course, there was nothing there.

"Doctor! Doctor! I'm here for my two o'clock appointment!" he announced, but there was no answer.

"Hey! Somebody, come let me in," he shouted. "The buzzer's gone and the building is too."

He stood for ten minutes staring up at the missing building.

"Ah, well. I guess there's nothing to be done about it," he mused, and lay down on the grass to take in the sunshine.
