   Frank and his brother Jack lived near the ocean. Frank was outgoing while Jack was shy. They liked doing different things. Frank was famous for organizing games of beach volleyball, football, and any other sport imaginable. Jack preferred to draw, paint, or build sandcastles（沙堡）.

Frank didn't understand why Jack would rather do artistic things than play ball. He believed sports often allowed many kids to play together. That was when Jack's idea hatched. He would show Frank what doing things together looked like!

After Jack finished creating a special sandcastle with stairs, towers and walls, he took pictures of it. Then he painted colorful posters featuring（突出）his sandcastle and the question, "Can you top this?" He hung his posters everywhere in town, announcing his plan for a day of sandcastle artistry-all ages welcome.

When Frank saw poster, he not so nicely told Jack that no one would come. Still, shortly after sunrise on Saturday, Jack was on the beach digging in the sand. By mid-morning, four kids were sculpting（雕塑）the sand alongside him. By noon the number had increased a lot.

After Frank came back from his ball game, he went to check how his brother's plan turned out. He couldn't believe what he saw. At least 30 people were building a city of sandcastles, and everyone was chatting and laughing and working together! It was the most beautiful thing he had seen on the beach.

"I guess you've proved me wrong," Frank said. "You should make this sandcastle day a yearly tradition!" Handing Frank a shovel（铲子）with smile, Jack got started together with his brother on their super creation in the sand.
