What is the proper punctuation for broken dialogue? I have the following line:
"I just never expected you to be so—" she looked Dan up and down "—human," she finished.
I believe that is the correct way to write that, but I'm not sure. Is there a comma before the dialogue resumes? Do I need spaces before and after the dashes, or are they right next to the words like I have them?
If you could point me in the right direction, that would be great.
