In course of joining a friend of mine during her NaNoWriMo escapades, I tried myself at actually writing a story set in a world I'm building.
I've found there are certain rules when writing a novel. E.g. moving to a new paragraph each time another person talks.
What I haven't yet found is any rule or consensus on how to stylize notes or book-passages that are being read by a character inside my story. I actually haven't found anything on the subject and I fear it's due to me taping into new territory, not knowing the proper words & designations for things.
I was considering doing something along the lines of putting the written bits into their own paragraph after indicating there being a note, or something else.
There was no Corbett, the chair he had occupied empty. The only sign of evidence that he had sat there just a minute ago was a note sitting on the counter:
Decided to leave before it gets hairy. Put it on my tab. Pleasure.
Is there any consensus on how to handle such things, or is what I am doing perfectly fine? What are commonly used alternatives?
