Most students are used to using social media, like email, text, instagram, and so on, to communicate quickly with friends and family. Social media breaks down barriers, which is a wonderful thing . . . but it also sometimes leads students to use some very unprofessional behavior when they email their teachers and – I assume – their bosses. This is not a wonderful thing. In fact, how you present yourself in email may affect how other people interact with you, and it definitely affects how they judge you.
