Hello, guys !
Dialogue. It’s a very useful tool for show don’t tell. But sometimes it sucks to see what some authors write. It hurts my eyes.
So, I give you an example to understand what I mean exactly:
“Have you stole my… there the book is!” Mary sees the book and grabs it.
“Have you stole my—,” Mary said but she sees the book lying on the table. “There it is.”

You know. The first example is shitty because it seems that Mary realize it while speaking and not like in the second one where she speaks first, interrupts because she realizes it’s lying there and speaks again. How can I avoid such confusing situations?
