Yea, my second post outside the introduction!
Anyway, I want to ask general advice when writing brief, but informative flashbacks of a main character. When would be a good time to set one, or to possibly discard it?
For instance in the story I'm writing my MC is fleshing a hide using a primitive bone tool. The task itself is a very focused, but repetitive process. So, her mind drifts to a couple years prior between the MC and her younger sister on a hunting trip and we glimpse an interaction between them. The point, I hope, would be inform the reader of the MC and family interactions with brief backstory.
