Snowy listened to the child crying. He sounded very distressed. She ran over and tore open a pack of paper towels to wipe away his tears and snot. She said, "Child, don't cry. Continue crying, and you will lose your voice."
The fat boy cried constantly when there was no one around. When a beautiful big sister came over to comfort him, he knew he'd had good luck and instead cried harder. He also gasped loudly, which simply added to the noise pollution.
