An English teacher at McKinley High School (city unknown) received a letter from one of her students that was taped to the door of the classroom, according to a posting on Reddit. The 101-word letter was full of grammatical and spelling errors, and also contained curse words and name calling directed at the teacher. And how did the teacher respond? By correcting all of the student’s mistakes. The teacher went through and sliced and diced the letter in red marker. And at the bottom, the teacher had one last smack down for the student by writing: "Please use your education appropriately. Proofreading takes five minutes & keeps you from looking stupid."
