I separate writing into steps, so work with me here, and read twice if you need to start over after the end. This is an excerpt from chapter thirteen in a writing of mine, so don’t read for content; read for basic instruction to help focus on one writing aspect at a time.
Personally, I like to write out my dialogue at once, using an abbreviation for who’s speaking, so I know who’s speaking when I come back. This way, I don’t have to worry about description, but I can simply concentrate on the art of conversation.
In this scene, my protagonist, Amea (A), is crying with her back to the door when Emmy (E) checks on her.
E—It’s Emmy.” “Are you crying?”
A—What are you doing here? Where’s Leena?
E—Still sleeping.” “I was in the garden. I don’t play much, but do you want to come with me?
Second: Conversational Description
This is where I separate the speech, so it sounds more realistic and/or add basic character descriptions.
“It’s Emmy,” she said, and I slid the door open as I wiped my tears away. She frowned. “Are you crying?” she asked, and I shook my head. “Good.” (I cut this dialogue to make it sound younger, as Emmy is nine.)
“What are you doing here? Where’s Leena?”
“Still sleeping.” Emmy shrugged “I was in the garden. I don’t play much, but—” She grinned with crooked teeth. “Want to come with me?”
Third: Further Description and Edit
This part is where I add the description, placing the basic scene and adding to the dialogue with scenic descriptions
I slammed my bedroom door and pressed my back against it, sobbing. Water curled down my fingers, and I clutched my face, falling to the ground. I laid my forehead on my shaky knees as my body shuddered, vibrating as knocking rocked my entrance. (All of this is added)
“It’s Emmy,” she said, and I scooted forward, (added necessary movement) sliding the door open as I wiped my tears away. She frowned, pulling at the ends of her curly red hair (added childish action), and rocked back and forth. “Are you crying?” she asked, and I shook my head. “Good.”
I smiled. “What are you doing here? Where’s Leena?”
“Still sleeping.” Emmy shrugged, pointing down the hall. (added—hall for scene) “I was in the garden. I don’t play much, but—” She grinned with crooked teeth. “Want to come with me?”
Four: EDIT EDIT EDIT.
It is necessary, so take that beautiful red pen of yours and get to work😀
I hope this may separate your writing into bits in which you can concentrate on important aspects one at a time, rather than worry all at once.
Have fun and write endlessly,
