Student physically attacks teacher who took away cellphone. But wait for the ending.

A video featuring a Texas student's assault on a teacher over a cellphone has gone viral — but it's the ending that might be the most shocking aspect of the entire ordeal.

What's in the video?

In the video, which Facebook user Chris Hunt shared on Tuesday, a student at a Cedar Hill, Texas, school can be seen approaching his teacher's desk and angrily shoving the teacher's papers off of the desk.

The student was reportedly angered because the teacher — physics teacher Bobby Soehnge — had taken the student's phone away during class, when the phone was not supposed to be out.

The unnamed student then can be seen grabbing Soehnge's face and neck and pushing him backward toward a whiteboard.

Soehnge can be seen calmly handing the phone over to the irate student, despite the student putting his hands on the teacher.

Hunt captioned the video, "Wow this happened at my daughters school today?? This is sad. Father’s [sic] We Gotta Raise These Young Men Better, But I commend the teacher because he handled it & he’s a better man than me!"

The video has been viewed over 1.4 million times and has been shared over 16,000 times.

What happened next?

Facebook user Hunt spoke with WFAA-TV, where he recounted his sadness over the filmed incident.

According to the station, Hunt and his daughter showed up at the school with gift bags for Soehnge.

"It broke my heart a little bit, to be honest," Hunt told WFAA. "I just want to let him know I appreciate him for how he handled that."

For his part, Soehnge told the station that his only thought during the encounter was to avoid making the situation worse.

"The important thing was to not add any energy into the dynamic that would make the situation more complicated," Soehnge said, noting that the student simply "lost his balance and acted out."

According to WFAA, the student was disciplined over his actions, but the story didn't end there.

So how did it end?

Principal Michael McDonald told WFAA that the student and teacher hugged it out after the incident and held a discussion.

"[Soehnge] actually met with the student after the class, they talked, they hugged," he said. "[Soehnge] spent a lot of time working with the student through the course of the year. They have a great relationship and that was just a bad day the student was having."

The school district reported that the student as well as his mother apologized for the incident.

The teacher also said he doesn't hold a grudge against the student over the incident.

"There's a way to solve complex problems whether it's in physics or even in life," he said. "I think because he was so willing to accept ownership and the consequences of his actions show that he's maturing — and that's what we always want as a teacher."
