Anger is a weird emotion. It’s very basic — compare it to envy or trepidation or love — but that does not mean it is necessarily easy to write. It can be both basic and enormously complex. Anger sucks. Being angry is hard and raw and weird. As with most things, even though the concept of anger is a simple one, the execution of it on the page is complicated and people often fail.
Translation: A lot of times dialogue that’s supposed to be angry comes off as flat. Oops.
Why is this though? We all know what anger is. We’ve all felt it at one point or another. Furthermore, we have all experienced many of the various shades and forms anger can take. Everyone over the age of ten has probably felt various nuances of anger. The anger you felt as a young child when your sibling was being a jerk is different than the anger you feel when a professor critiques your work in front of the class. This, in turn, is different than the anger you feel when you believe a partner may be cheating on you. Maybe all these things make you scream, but they’re all different and all stem from different places.
