The article ” U Can’t Talk to Ur Professor Like This ” by Molly Worthen. The author points out that students should respect their teachers and call them professor with last name instead of just call the first name. When students email to professor must proofread and in formal ways. Also the author mentions that in many workplace,most of people call their C.E.O or manager by first name.
