When writing a character's thoughts is there a correct way to do it, or is it down to peronal prefereance? For example: Veronica let her go. She knew this act well. Danielle was the best at this kind of manipulation. Not this time, little sis, Veronica thought, I'm not falling for this act. She watched her sister and wondered if she'd march on out of her life forever and forever indignant. She took maybe ten strides before she turned back. In this example I have used the thought like speech minus the speech marks. I have seen this often in books. The other example is to write in italics to emphasise that it's not normal speech, nor part of the descriptive text. I have seen this example just as often. Which is correct?
