When a Rockaway, New Jersey man went to his 11-year-old son's back-to-school night, he took some photos of his son's work, spoke to the teachers and went home.
Then, it hit him.
As Bob Cornelius looked at a photo he had taken of his son Christopher's classwork, the words "no one" were "like a punch in the gut," he told ABC News.
The question Christopher had answered was "Some of my friends are..."
"No one." His son, who isn't exactly like other kids, has no friends.
"Never have five letters cut so deep, and they weren't even directed at me," Cornelius wrote in a Facebook post. "It was just an overly simplistic statement that spoke volumes."

Cornelius explained that his 11-year-old son is on the autistic spectrum and it isn't that the other students are overtly mean to Christopher, but excluding him is just as cruel.
Cornelius told ABC News he hoped his post "starts a conversation" and that parents start talking to their kids about including kids who might be different.
