A Florida high school teacher has recently come under fire after a student's science homework assignment was returned to him with the comment "WTF is this?" written in red pen at the top of the paper, New York Post reported.
I'm sure there are a lot of things teachers think while grading students' papers, and I'm also sure they're not all positive or constructive in nature. But that doesn't mean they should pick up their pen and write those uncensored thoughts on the paper.
