What is handled
A note on writing: if you can imagine that you are watching a movie at home, you’re following the story. You’d want to watch that story on a nice, modern TV with good sound, a good picture too, well that is what grammar does, conveys the story. If your grammar is unclear, or hazy, or just poorly-written, then the reader won’t get the story. Poorly-written writing annoys because it would be like the TV losing its sound at parts or the screen breaking up. Thus, as a result, it is imperative to write well. Naturally, you also want a story that has gold in it.
