Donna’s two daughters were going to school soon. She decided to buy them water bottles. She bought a pink one and a blue one. Then she drove back home.
“Girls! I have something for you!” the mom said. Sarah and Barbara ran to her. “What is it?” Sarah asked. Donna showed them the water bottles. The girls both picked the pink one. They started pulling it. “I picked it first!” Barbara said. “I did!” Sarah argued.
The mom did not know what to do. She thought one of them would like the blue one. She could just flip a coin (掷硬币). One of them would still be sad though. So Donna decided not to give the water bottle to any of them.
