How do I stylize a conversation going on in written notes. Two students are passing notes in class, and it goes something like this: Kid 1 wrote, Hey, how's it going? Kid 2 rolled his eyes. I felt so sick at the party, I went home and puked on the cat. Now there are puke footprints all over the house. Kid 1 chuckled. Better than my night. I thought Brad was my girlfriend. Guess what I did. I'm not guessing. I'm forgetting you brought that up. The exchange isn't that awful, but this gets the idea across. Should I add "dialog" tags (he wrote, she wrote), italicize the words (I doubt it)? Is the above all right and I should trust the reader to tell the difference between the action and the dialog? Sometimes I don't add anything, like that last line. What's the deal here? Same with thoughts. I find it ridiculous to always say "he/she thought." Sometimes the thoughts flow straight from exposition/action, so I don't want to start a new paragraph. Should I trust that the reader can tell the difference? I know italics and quotation marks are no-nos. Can someone suggest a literary device I can use or are readers smart enough?
