static const char UPLOAD_STRING[] =
"It was almost December, and Jonas was beginning to be frightened. No. Wrong word, Jonas thought."
"Frightened meant that deep, sickening feeling of something terrible about to happen. Frightened was"
" the way he had felt a year ago when an unidentified aircraft had overflown the community twice."
" He had seen it both times. Squinting toward the sky, he had seen the sleek jet, almost a blur at"
" its high speed, go past, and a second later heard the blast of sound that followed. Then one more time,"
" a moment later, from the opposite direction, the same plane. At first, he had been only fascinated. "
"He had never seen aircraft so close, for it was against the rules for Pilots to fly over the community."
" Occasionally, when supplies were delivered by cargo planes to the landing field across the river,"
" the children rode their bicycles to the riverbank and watched, intrigued, the unloading and then the "
"takeoff directed to the west, always away from the community. But the aircraft a year ago had been different."
" It was not a squat, fat-bellied cargo plane but a needle-nosed single-pilot jet. Jonas, looking around"
" anxiously, had seen others — adults as well as children — stop what they were doing and wait, confused,"
" for an explanation of the frightening event. Then all of the citizens had been ordered to go into the nearest"
" building and stay there. IMMEDIATELY, the rasping voice through the speakers had said. LEAVE YOUR BICYCLES "
"WHERE THEY ARE. Instantly, obediently, Jonas had dropped his bike on its side on the path behind his family's "
"dwelling. He had run indoors and stayed there, alone. His parents were both at work, and his little sister,"
" Lily, was at the Childcare Center where she spent her after-school hours. Looking through the front window,"
" he had seen no people: none of the busy afternoon crew of Street Cleaners, Landscape Workers, and Food "
"Delivery people who usually populated the community at that time of day. He saw only the abandoned bikes here "
"and there on their sides; an upturned wheel on one was still revolving slowly. He had been frightened then. "
"The sense of his own community silent, waiting, had made his stomach churn. He had trembled. But it had been "
"nothing. Within minutes the speakers had crackled again, and the voice, reassuring now and less urgent, "
"had explained that a Pilot-in-Training had misread his navigational instructions and made a wrong turn. "
"Desperately the Pilot had been trying to make his way back before his error was noticed. NEEDLESS TO SAY, "
"HE WILL BE RELEASED, the voice had said, followed by silence. There was an ironic tone to that final message, "
"as if the Speaker found it amusing; and Jonas had smiled a little, though he knew what a grim statement it had"
" been. For a contributing citizen to be released from the community was a final decision, a terrible punishment,"
" an overwhelming statement of failure. Even the children were scolded if they used the term lightly at play, "
"jeering at a teammate who missed a catch or stumbled in a race. Jonas had done it once, had shouted at his "
"best friend, &quot;That's it, Asher! You're released!&quot; when Asher's clumsy error had lost a match for "
"his team. He had been taken aside for a brief and serious talk by the coach, had hung his head with guilt and "
"embarrassment, and apologized to Asher after the game. Now, thinking about the feeling of fear as he pedaled "
"home along the river path, he remembered that moment of palpable, stomach-sinking terror when the aircraft had"
" streaked above. It was not what he was feeling now with December approaching. He searched for the right word"
" to describe his own feeling. Jonas was careful about language. Not like his friend, Asher, who talked too "
"fast and mixed things up, scrambling words and phrases until they were barely recognizable and often very funny. "
"Jonas grinned, remembering the morning that Asher had dashed into the classroom, late as usual, arriving "
"breathlessly in the middle of the chanting of the morning anthem. When the class took their seats at the "
"conclusion of the patriotic hymn, Asher remained standing to make his public apology as was required. "
"&quot;I apologize for inconveniencing my learning community.&quot; Asher ran through the standard apology"
" phrase rapidly, still catching his breath. The Instructor and class waited patiently for his explanation."
" The students had all been grinning, because they had listened to Asher's explanations so many times before. "
"&quot;I left home at the correct time but when I was riding along near the hatchery, the crew was separating "
"some salmon. I guess I just got distraught, watching them. &quot;I apologize to my classmates,&quot; Asher"
" concluded. He smoothed his rumpled tunic and sat down. &quot;We accept your apology, Asher.&quot; The class"
" recited the standard response in unison. Many of the students were biting their lips to keep from laughing."
" &quot;I accept your apology, Asher,&quot; the Instructor said. He was smiling. &quot;And I thank you, because "
"once again you have provided an opportunity for a lesson in language. &quot;Distraught' is too strong an adjective"
" to describe salmon-viewing.&quot; He turned and wrote &quot;distraught&quot; on the instructional board. "
"Beside it he wrote &quot;distracted.&quot; Jonas, nearing his home now, smiled at the recollection. Thinking, "
"still, as he wheeled his bike into its narrow port beside the door, he realized that frightened was the wrong "
"word to describe his feelings, now that December was almost here. It was too strong an adjective. He had waited a"
" long time for this special December. Now that it was almost upon him, he wasn't frightened, but he was ... eager,"
" he decided. He was eager for it to come. And he was excited, certainly. All of the Elevens were excited about the"
" event that would be coming so soon. But there was a little shudder of nervousness when he thought about it, about"
" what might happen. Apprehensive, Jonas decided. That's what I am. &quot;Who wants to be the first tonight, for "
"feelings?&quot; Jonas's father asked, at the conclusion of their evening meal. It was one of the rituals,"
" the evening telling of feelings. Sometimes Jonas and his sister, Lily, argued over turns, over who would get to go first."
" Their parents, of course, were part of the ritual; they, too, told their feelings each evening. But like all parents — "
"all adults — they didn't fight and wheedle for their turn. Nor did Jonas, tonight. His feelings were too complicated this evening.";
