I... Am the hated other. Because I very very infrequently go back and add in more detail, or edit out detail, unless for some reason or another I feel like I need to change up something I wrote. I almost never edit - I'm a one and done.
Buy when I do feel a need to edit, like when I write something I intend to get feedback on, that's when I'll go in and both add stuff, and delete other stuff. I definitely need to work on adding in more setting - I usually rely heavily on character dialog and introspection to carry what I write, especially with Nevin. With Erik and Hunter I'm leaning more onto action stuff which I hope is helping.
