In grade 6, my teacher Miss Chess used a green pen. She found red was too bold and offensive. She would do her corrections in a soft green ink. I liked that a lot. It was soothing for a person like me, who made a tremendous amount of spelling errors. It’s easier to look at a paper filled with green ink corrections than redly inked marks. After a great year of learning with Miss Chess, I decided green ink was the way to go when I played school with my friends. Now as a university instructor, I still correct in green ink and pencil.
