I'm writing a short story for my honors English class (I'm in 9th grade). I am writing it in 3rd person omniscient. At several different points in the story, the main character is thinking. I'm not sure how to show the thoughts. I've been using italics, but am I also supposed to use quotation marks as well? I know I've seen it done different ways in different books, but what is the most commonly accepted way, as my teacher is very strict?
Thank you!!
