Remember when President Donald Trump tweeted the word letters “covfefe” and basically caused a Twitter meltdown? Well, imagine receiving a letter from the president that’s riddled with grammatical errors.

Yvonne Mason, a Democrat and retired high school English teacher, wrote a letter to Trump asking him to visit with family members of the victims of the Parkland school shooting. The White House responded with a letter of their own signed with Trump’s name. But according to Mason, it was full of mistakes.

Mason, who taught middle and high school in South Carolina for 17 years, said that the letter was so bad it would probably not have received a passing grade if one of her students had written it.

“I have never, ever, received a letter with this many silly mistakes,” Mason told The Greenville News on May 25th. “If it had been written in middle school, I’d give it a C or C-plus. If it had been written in high school, I’d give it a D.”

Mason couldn’t resist correcting the letter’s grammatical mistakes and sending it back to the White House. “Have y’all tried grammar and style check?” she wrote at the top. Burn.

Mason posted a photo of the letter on Facebook, complete with her edits in purple ink.

Though she acknowledges that the letter probably wasn’t written by Trump himself, she said she still expected more from the White House. Not only were there errors, but the letter didn’t even specifically address her concerns. Instead, it outlined the president’s actions on gun control.

Moral of the story: Donald Trump – or whoever writes his official letters – should invest in a working spell checker.
