When firefighter Lt. Mike Rheault saw a young boy standing in the hallway of a building he was responding to, he noticed the boy looked like he wanted to say something. Tegan McCall has cerebral palsy and is nonverbal, so he could not speak. But when Rheault began signing to him in an effort to communicate, McCall's face lit up, and the two started signing to each other. McCall's mother recorded the conversation and uploaded it to social media, where it gained more than 20,000 views.
Watch the video above to see the conversation between McCall and Rheault, and find out how much it meant to McCall and his mother.
