Mitchell Wollen, 15, is a good swimmer and a second-year student at a high school in US. When swimming stopped and the school shut down because of the COVID-19, he found that he had a lot of free time.

"My friend and I were brainstorming (集思广益) ," said Wollen. "We thought we'd make these hearts for people on the frontline who are doing everything for us."

Wollen first made a red wooden heart with the words "Thank You" painted on the front. His mother Julie posted a picture of the heart online on April 5.

After that, Wollen didn't have any more free time. He had 100 orders for his heart signs in the first week. He had to cut out the signs with a knife, paint them and deliver (寄送) them.

When online learning started up at the school, Wollen had to do schoolwork for six or seven hours a day before finding time to work on the signs.

Wollen has asked people to donate whatever they can for the signs. So far, he's raised about 1,600 dollars, which he will use to buy meals for medical workers.

He's talked with workers at Gaylord Hospital in Wallingford. His mother has a friend with a coffee truck, so he pays the people who run the truck to go to Gaylord and give the workers free coffee.

"Everybody's having a hard time right now," he said. "I just want to help those who are struggling in these times."
