Vivian Keith, 2, was diagnosed in February with acute lymphoblastic leukemia, which damages cells that help fight infection. While Vivian was undergoing chemotherapy at St. Louis Children’s Hospital, her mother, Ginger Keith, saw two construction workers aiming for their attention through the hospital window.

"They were waving like crazy at us and pointing at the beam and it had 'get well soon' written on it," Keith said to Today. "It's hard for [Vivian] to grasp the extent of it, but we know. And I know she's not the only one they were waving at — a lot of kids play in the window. It just means so much. That they're taking the time, that they're doing this for the kids.”

The construction was part of an expansion project with Barnes-Jewish Hospital, according to Today. Keith and her daughter enjoyed observing the workers in action.

"We've always watched the construction, from day one since we've been there," Keith told Today. "Vivian likes to hang out in the window and play with her figurines. She likes to wave and we watch the crane. And sometimes we get a wave back."

The two construction workers, Greg Combs and Travis Barnes, “just wanted to cheer the young girl up,” according to Today.

"We're the two guys up on the building that the crane brings beams to, so we're pretty close to her window," said Combs to Today. "She was waving at us and we were waving back and forth, and this went on for a day or two. One day, I just radioed down to one of the guys on the ground and said, 'Hey, write 'get well soon' on this next beam.’”

The two men recently met with Vivian and her family.
