I was wondering about how to express thought in my writing. I normally use single quotation marks around the thought ('I wonder what is for dinner?') and double quotation for speech ("I'm going to get a burger."). But I've seen others separate thoughts in different ways, such as italics. So I was wondering which one I should use, and with way would be expected by a publisher if I ever decide to try and publish a story. What do you guys think? P.S.: Sorry about the food examples. As you can tell I'm kinda hungry at the time of posting.
