A Massachusetts woman allegedly said she only intended to scare her father with a knife when he suddenly threw himself into the weapon following an argument over a Facebook post, according to reports.

Kelsey Gaulin was accused by her father of making a critical reference of him on the social media website, her brother told police. Following the dispute between the pair at their home in Palmer – 75 miles west of Boston - the 27-year-old walked into her father’s bedroom with a knife, the report said.

“I was going to say something to him like be quiet, but before I could he threw himself into the knife,” she wrote in her statement to police, according to MassLive.com. “I was still holding it and I saw his eyes get real wide open. I kept saying ‘I’m sorry. I was holding a knife.'”

Jerry Gaulin was treated for a serious chest wound but is expected to survive. He told police the knife was four to five inches long. Authorities found the weapon on his daughter’s dresser.

“I know I went too far tonight,” she wrote in a police statement obtained by the news site. “I know that even trying to scare him, I went too far.”
