Robb Scott was in a store looking for a movie to watch on Saturday when he overheard a boy ask his father, "What's Down syndrome?"
Scott said the father told his son it was "an illness of not knowing anything."
"I didn't think his dad was trying to be mean," Scott said. "I could see he was searching for the right thing to say."
Scott posted a video to Facebook detailing the story because he regretted not explaining what Down syndrome is to the boy and his father.
Scott's son, Turner, has Down syndrome.
"I heard that voice in my head saying, 'Tell them what it is,' and I didn't. I let that ignorance grow in another generation and failed my son in the process."
"Down syndrome is one of the most beautiful things to happen in my life," Scott said. "It is not an illness. It is not even a disability."
The video has been viewed over 1 million times.
Scott is overwhelmed by the response.
"If 10 people heard it, then I could feel better," Scott told The Washington Post Friday. "I thought maybe five or 10 people might share the video. But what's happened has really been astonishing. I'm still at a loss for words why this video seems to have struck such a deep chord."
Watch the father's emotional video below.
