They agreed passionately out of the depths of their tormented lives. - William Golding

"We can use this to call the others. Have a meeting. They’ll come when they hear us—"
He beamed at Ralph.
"That was what you meant, didn't you? That's why you got the conch out of the water."
Ralph pushed back his fair hair.
"How did your friend blow the conch?"
"He kind of spat," said Piggy. "My auntie wouldn't let me blow on account of my asthma. He said you blew from down here." Piggy laid a hand on his jutting abdomen. "You try, Ralph. You'll call the others."
Doubtfully, Ralph laid the small end of the shell against his mouth and blew. There came a rushing sound from its mouth but nothing more. Ralph wiped the salt water off his lips and tried again, but the shell remained silent.
"He kind of spat."
Ralph pursed his lips and squirted air into the shell, which emitted a low, farting noise. This amused both boys so much that Ralph went on squirting for some minutes, between bouts of laughter.
"He blew from down here."
Ralph grasped the idea and hit the shell with air from his diaphragm. Immediately the thing sounded. A deep, harsh note boomed under the palms, spread through the intricacies of the forest and echoed back from the pink granite of the mountain. Clouds of birds rose from the treetops, and something squealed and ran in the undergrowth.

We did everything adults would do. What went wrong?

Ralph heard the great rock long before he saw it. He was aware of a jolt in the earth that came to him through the soles of his feet, and the breaking sound of stones at the top of the cliff. Then the monstrous red thing bounded across the neck and he flung himself flat while the tribe shrieked.
The rock struck Piggy a glancing blow from chin to knee; the conch exploded into a thousand white fragments and ceased to exist. Piggy, saying nothing, with no time for even a grunt, travelled through the air sideways from the rock, turning over as he went. The rock bounded twice and was lost in the forest. Piggy fell forty feet and landed on his back across that square, red rock in the sea. His head opened and stuff came out and turned red. Piggy's arms and legs twitched a bit, like a pig's after it has been killed. Then the sea breathed again in a long, slow sigh, the water boiled white and pink over the rock; and when it went, sucking back again, the body of Piggy was gone.
This time the silence was complete. Ralph's lips formed a word but no sound came.
Suddenly Jack bounded out from the tribe and began screaming wildly.
"See? See? That's what you'll get! I meant that! There isn't a tribe for you any more! The conch is gone —"
He ran forward, stooping.
"I'm Chief!"
