This letter from a fourth-grade elementary student is just another example of how it's a small world, after all.

Before Jim Johnson became the sheriff of the Ozaukee County Police Department in Wisconsin, he was a soldier stationed in Iraq and Afghanistan.

While he was deployed, Johnson received dozens of letters from American school children - and he kept every single one of them as a reminder of the kids who cared about him while he was stationed overseas.

The police officer was recently going through his collection of heartwarming letters when he found one that had been written by a young student from Cedar Grove Belgium Elementary School in Wisconsin.

The letter read: "Dear soldiers. Thank you for what you all do and are doing for our country. Best wishes and have a Merry Christmas. From Chris Uselding."

Johnson was immediately stunned by the letter: Chris Uselding, the young student who had written the reassuring note, had been working alongside Johnson at the police department for several years.

"It's crazy to think about that this letter touched Sheriff Johnson and he was able to share that with me and keep it for all these years," Uselding told WDJT.

The sheriff added: "It makes you realize how small the world is. It truly does."
