In the fall of 2016, my first semester of college ever, I took a Scriptwriting class with Andrew McAllister. We focused a lot on showing the story through character actions and mannerisms and through implications, rather than telling the reader what was going on directly.
I.e. “Oh my goodness, Sally, I can not believe that you killed my father! I feel so guilty now that I know this information!” Instead, we would show the character crying, possibly biting her nails, hunched over, and shifting her eyes a lot to portray guilt.
The “Mute Office” story was meant to tell a strictly visual story without polluting the narrative with unnecessary jibber jabber. So, we were instructed to strictly SHOW feelings, emotions, and situations.
