Halfway across the park she stopped to take off her cardigan. As she bent over to pick up her tennis racquet again someone touched her on her freshly bared arm. Christine seldom screamed; she straightened up suddenly, gripping the handle of her racquet. It was not one of the old men, however; it was a dark-haired boy of twelve or so.

“Excuse me,” he said, “I search for Economics Building. Is it there?” He motioned towards the west.

Christine looked at him more closely. She had been mistaken: he was not young, just short. He came a little above her shoulder, but then, she was above the average height; “statuesque,” her mother called it when she was straining. He was also what was referred to in their family as “a person from another culture”: oriental without a doubt, though perhaps not Chinese. Christine judged he must be a foreign student and gave him her official welcoming smile. In high school she had been president of the United Nations Club; that year her school had been picked to represent the Egyptian delegation at the Mock Assembly. It had been an unpopular assignment—nobody wanted to be the Arabs—but she had seen it through. She had made rather a good speech about the Palestinian refugees.

“Yes,” she said, “that’s it over there. The one with the flat roof. See it?”

The man had been smiling nervously at her the whole time. He was wearing glasses with transparent plastic rims, through which his eyes bulged up at her as though through a goldfish bowl. He had not followed where she was pointing. Instead he thrust towards her a small pad of green paper and a ballpoint pen.

“You make map,” he said.

Christine set down her tennis racquet and drew a careful map. “We are here,” she said, pronouncing distinctly. “You go this way. The building is here.” She indicated the route with a dotted line and an X. The man leaned close to her, watching the progress of the map attentively; he smelled of cooked cauliflower and an unfamiliar brand of hair grease. When she had finished Christine handed the paper and pen back to him with a terminal smile.
