Meet Vincent Butterfield and Zac Gossage, two first graders from Union, Missouri.
There's no mistaking it.
But if there was ever any doubt their bond went deep, it went away when Zac was diagnosed with leukemia last June.
Leukemia is an aggressive blood cancer that, according to the American Cancer Society, accounts for almost 1 in 3 cancers diagnosed in children and teens.
"It's when your white blood cell and red blood cell fight," Vincent explained to WTNH News 8.
But what this little trooper did for his friend next left us all speechless. After finding out that Zac's chemotherapy was very expensive, Vincent raised $200 dollars by selling scarves. For a 7-year-old, that's a lot of money. But he didn't stop there. When he learned that Zac's treatment was going to cause him to lose his hair, Vincent shaved his off.
"I cut it off," Vincent explains in WTNH's interview as if it's the most obvious thing ever. "To make Zac feel like he's not the only one without hair."
Everyone could use a best friend like that.
