You’re, Your, Then and Than. Its easy to learn. Why do people misuse these words the most? You might have noticed I dont use apostrophies because I think theyre useless visually (there are instances where they must be used such as “we’re” and “were”). I do that because Im sick of people who get online thinking that you dont have to use capitalization for the beginning of their sentences. The Internet is formed and that gives humanity to butcher the English language? Now…I dont profess to be the best writer/speller. I was in a special class for spelling with Nuns and rulers when I was growing up and I will never forget trying to make my printing as perfect as possible so at least they couldnt hit me for that reason, but I do find it rather damning when people cant use those four words properly. Its rather telling.
