An unlucky California skateboarder found out the hard way that some mothers react very aggressively when they see their children get hurt, even if it is by accident.

While shooting a segment for a skateboarding mixtape series earlier this month at a local skatepark in California, professional skateboarder Leland Goldberg did not notice that a child was on the loose.

Goldberg ended up accidentally smashing into the young child, knocking him flat on his back.

“I’m sorry, man,” Goldberg said after the collision.

“Did you not see him?” asked a woman who was near the accident.

“I did not see him. I was looking down,” he responded.

That’s when the boy’s mother showed up.

“Did you run into my son?” she shouts. “On his birthday?”

She continued: “You didn’t see him?”

Before Goldberg had a chance to say anything, the mother hauled off and clocked him square in the face:

The video, which was posted earlier this month to YouTube, has attracted more than one million viewers and achieved “viral” status:

Luckily, the situation didn’t escalate as Goldberg chose to walk away.

“Walking away was the smart move on Goldberg’s part. Right or wrong, this mother couldn’t be reasoned with at the time, and further conversation likely would’ve only provoked her more,” Dan Carson writes for Bleacher Report.

“Let it be known that allowing your toddler to run amok at the skatepark without a helmet, pads or supervision is probably not a winning proposition,” Carson adds.
