The notes were spread over a letter signed by President Trump.
In the upper left corner: "Did you try grammar and style checks?"
Top right: "Federal is activated only when used as part of a nickname."
And down: "OMG, this is FALSE!"
The letter dated May 3, printed on stationery The White House was addressed to Yvonne Mason, 61, a former High School English teacher who had retired last year but had not quite left grading paper mode, she said Sunday.
When she received the letter in the mail, she pulled her go-to-purple pen and began making corrections. Then she took a picture, wrote the letter on Facebook and sent it back to the White House.
"It was a poorly worded letter," she said. "Bad writing is not something I follow, if someone succeeds in doing it better then they should do better."
Woman. Mason, a Democrat living in Atlanta, had written to Mr. Trump to ask him to visit each family of those who died in the shooting in February 17 people at a school in Parkland , Florida, died  "I wrote to them in anger to tell you the truth," she said. "I thought he owe it to those grieving families."
The letter she received did not address her concerns, she said. Instead, a series of post-shooting measures were taken, such as hear sessions, meetings with lawmakers, and the STOP school violence act, which approved $ 500 million over 10 years for safety improvements in schools, but no provisions regarding Contained weapons.
A phrase about a "rule" that prohibits equipment that make legal weapons illegal machine guns was unclear. "Explain the rule," she wrote.
There was more, but she did not correct everything. "I did not mention the modifier," she said. "I focused mainly on mechanics."
"Nation" was capitalized, as well as "States". Mrs. Mason circled both.
However, a style manual calls for the federal government to capitalize on "nation". and "Federal" if the words are used as a synonym for the United States. It means "state" should be capitalized if it refers to the government or the legislature. In letters from Presidents Barack Obama and George W. Bush, written online, words such as "nation" and "president" are capitalized.
The White House did not respond immediately to a request for comment.
The letter contrasted with other letters she received from politicians, said Ms. Mason. Senator Lindsey Graham, Republican of South Carolina, sent "beautiful" letters that set a tone that "makes me more important than him," she said.

After a New Year's resolution, she wrote a postcard to the White House every day since January 1, she said.
When she taught, she wanted to show her students that their votes counted, even if they were not old enough to vote, she said.
"You're important, you have to be a part of it, you have to be careful what's going on," she said.
When the word spread about the corrected letter she sent to the White House, Ms. Mason received hundreds of messages from people across the country – some positive (a lawyer in Houston wanted to know if she would be interested, to look over his appeals documents) and other venomous ones (one person suggested she "must be a lonely bitter witch with many cats"). 19659002] But Ms. Mason did not focus on the negativity.
"Let her have her day, bless her little hearts," she said. "You do not change my mind."
