If you love something enough but lose it, it may just find its way back to you.

That’s a lesson a Connecticut man learned this week, when he miraculously (神奇地) recovered a dollar bill that his wife had signed years before.

Peter and Grace Bilillo were married for 50 years before Grace lost her battle with cancer. They first met in Peter’s home in Sicily when his mother introduced her unmarried son to the pretty girl down the street.

It was love at first sight. “We got married in 40 days,” said the 86-year-old man.

About seven years ago, the devoted couple each took a dollar bill and signed the names - Grace on one and Peter on the other - as a sign of their love.

“I said, ‘This dollar bill is going to be in my wallet forever,”’ Peter Bilillo said.

Forever didn’t last as long as Peter hoped, though - two years after signing the two bills, he fortuitously spent them. When his wife died, he was heartbroken.

“I felt sorry, very sorry. I thought we were never going to see those two dollars back again,” he said.

So, imagine Peter’s surprise when seven months after his beloved wife’s death, he took his granddaughter to a local subway shop, glanced at the change handed back to him by the cashier and saw his beloved Grace’s name staring at him from one of the dollar bills.

“I never thought I was going to get that dollar back again,” he said. “The first thing I said was, ‘Grace, she did this to make me happy.’”

“It’s a miracle to get it back,” he told reporters. “Who knows how many millions of people got that dollar in their hands?”

Peter says he hopes that, with a little help from Grace, the dollar with his signature will make his way back to him as well.

Her encouragement seemed to work wonders. Even more students began to hand in their homework, and studied much harder than before.

Li says she believes in the strength of "the devoted style of teaching and schooling". "Compared with knowledge, the students are more eager for an emotional connection and the feeling of being cared for," says Li.

Guo Yanhong, a student of Li, came to her office almost every day and asked Li to check his homework or explain problems. Sometimes he even seemed to be quite happy if Li criticized him for making mistakes.

By talking to Guo, Li got to know his mother had left home when he was young, and his father went far away for work.

One day, when Li was examining Guo's homework, she saw a wound on his hand, and reminded him to dress it to prevent infection. Her caring words hit Guo hard. He later wrote in an essay that he turned around and burst into a flood of tears upon hearing Li's words.

"After reading his composition, I thought it was too exaggerated（夸大的）. How can someone be moved so much by such simple words? So I reminded my students not to fake（掩饰） emotions in their compositions and that they need to express their true feelings," says Li.

But at her last class at Hanji school, when she asked if any student wanted to say something to her, Guo put up his hand first and said: "Ms Li, I didn't fake my emotions in the composition. All that I wrote was true. Maybe you thought what you said were simple words, but for me, who has never received much care, you were just like my mother in that moment."

Li still feels regret for her misunderstanding of Guo.

"Guo made me understand that I should pay more attention to my way of talking to students, since a teacher's words can be really influential," she says.

When Katie Stagliano was 9 years old, she was given a class project to grow her first cabbage from just one seed. She took it home and planted it in her home garden. It didn’t even take her long to come up and begin to grow. But as friends came over, they pointed out that it was bigger than any of theirs. And it grew so much that the cabbage ended up weighing 40 pounds! Katie then decided that she could use this cabbage to do something nice for the community. So she took the huge cabbage to a local soup kitchen, where they used it, and cooked it with ham and rice. And because of her cabbage, 275 people were fed.

She began to realize that gardening and helping people is what she likes to do most. So, she decided to start her first garden on a plot of land donated by her school.

“I think if more kids get to experience gardening they would find out how cool it is and how many people can be fed if you donate your produce,” said Katie. Now, just 9 years later, Katie is 18 years old, and has set up her own business called “Katie’s Krops” with the help of her family friends.

But this doesn’t even come close to the other amazing part. She has raised over 200,000 dollars! And there are over 100 Katie’s Krops within 33 states in the United States. She loves gardening and loves inspiring other children to experience the joy of gardening as well. As of today, her first garden is still doing amazing and is even responsible for supplying over 3,000 pounds of produce donated to local charities. Her goal now? To get 500 gardens across all 50 states.
