Imagine losing touch with your sibling as a young child, and never seeing them again. You grow up never knowing exactly what happened to them or where they are, and as far as you know, there's no way to find out.
And then social media comes along.
This week, two different stories of siblings separated for decades and then reunited by social media hit the web.
The first is the story of Tanija Delic, 88, and Hedija Talic, 82, two Bosnian sisters who lost track of each other almost 72 years ago when Talic got separated from her family while they were fleeing their village at the start of World War II.
These days, it turns out the sisters only live about 200 kilometres apart. But neither one had any idea, until Talic's son got interested in his mother's story and tracked down her sister with the help of Facebook.
Hedija wasn't on Facebook, but her daughter was. Talic's son got in touch with her, and they arranged a meeting.
The sisters shared "tears and disbelief" when they saw each other again after so many years apart. They told local media in Bosnia that they share memories of "the smallest events from childhood."
They're not stopping with meeting each other - now they're planning to trace their brother or his family, who they believe live in the United States.
And the second story is from the U.S., where Florissant, Missouri resident Betty Billadeau was reunited with her little brother, Clifford Boyson, 65 years after losing touch with each other.
On Tuesday night, they saw each other for the first time since Betty was five years old. And it was all thanks to an 8-year-old.
The two siblings were sent to different foster homes growing up in Chicago when they were small children. Although he's looked for her regularly in the six decades since, Clifford has never managed to find her.
This time, he had help. Eddie is an 8-year-old boy whose parents are friends with Clifford. Apparently it took him a week to track down Betty on Facebook.
She was happy to see her little brother again.
"I knew he was there, but not where he was at, and it just - it's a hole in your heart, I guess," Betty says in the video above.
They've met via iPad, and they're planning a face-to-face meetup in Iowa this weekend.
So there you have it. Sometimes technology succeeds in bringing people closer together, even when they've been apart for a really long time.
