Standard English is one of three forms: Proper English, Standard English, and Common English. Until very recently, Standard English encompassed all of normally used English, however, as many forms of communicating on the internet have separated away from normal use, many of the less formal grammar styles and uses (i.e. caps lock, texting abbreviations, etc.) have been classified as Common English. However, any conversation you have with a pre-Millennial will use Standard English, even if it's "Hey, how's it going?" If you are talking to a superior, you will also be using Standard English.
