A retired high school English teacher shared that a letter sent to her from President Trump, would've hardly earned a passing grade, so she made edits to the letter and sent it back to the White House, The Hill reports.

Atlanta resident Yvonne Mason corrected a number of grammatical mistakes in the letter, including Trump’s signature, and improper capitalization of words like “president” and “state.”

Mason taught middle and high school in South Carolina for 17 years. “If it had been written in middle school, I'd give it a C or C-plus,” Mason told South Carolina's Greenville News. “If it had been written in high school, I'd give it a D.”

She didn't include a grade when she sent the letter back to the White House.

She says she understands that the letter was probably written by a staff member. She had initially written the letter to ask that Trump meet individually with the families who were victims of the Parkland shooting on Feb. 14.

“When you get letters from the highest level of government, you expect them to be at least mechanically correct,” she told Greenville News.

“It's stylistically appalling,” she added, relating Trump’s letter to the “exquisite” letters she was sent from South Carolina Sen. Lindsey Graham's (R) office. 

Mason said that the White House didn't respond to her original inquiry.
