Kindergartens may teach you very important things you need to know. Dancy, a 5-year-old boy, saved his father’s life with the skills he learned.

The boy’s father became seriously ill on the way home from a father-son shopping. He couldn’t speak and could hardly move, but he tried hard to stop the car safely. At that point, Dancy used his father’s phone to call his mother for help. The 5-year-old boy tried his best to give her useful information and he was able to tell where they were. Just as he had learned in the kindergarten, Dancy read the letters he saw on a nearby store sign: “F,U,R,N,I,T,U,R,E.” But that wasn’t enough for his mother to find them. Then he added that they were near a bridge. Finally, his mother understood he was talking about a store called Furniture 22 on New Jersey’s Route 22. The mother called 911 and the father was saved in time.

“He just thought his dad needed help,” Dancy’s mother told the reporter. She also pointed out that her husband was a hero, too. “It is surprising for him to get off the highway and get himself and his child to safety even when he was so sick,” she said.

Shine, head of the kindergarten, felt proud of his pupil. “Dancy’s spelling skills helped him seize（抓住）the moment,” he said. “And that’s the real value of education.”
