We've all had a friend that ends up feeling like family. It's part of life.
But according to the Huffington Post, the line between friend and family is even more blurry for two Canadian men.
Duncan Cumming and Ron Cole were both adopted when they were younger and were best friends in the 1950s. They were exceptionally close when they were young but later drifted apart. The pair is now reconnected, but not for a reason anyone would imagine.
"We were chums in public school for about two or three years, not knowing that we were brothers," Cumming said. "It's unbelievable."
The pair will be reunited next month in Ottawa, Canada.
