Here is a little list for you guys on how to show anger without having your character proclaim YOU MAKE ME SO ANGRY!
have their jaw and/or fists clenched
have their "eyes narrow dangerously"
have their nostrils flare
have their muscles tighten/jaw tighten
have their lips press in a straight line
have them take a shot - or really, do anything - in an aggressive manner
have their tone of voice be tight
have them strain to speak nicely
have them give an "obviously fake" smile
have them size the other person up
have them square up to the other person
have them slam down the receiver (when talking on the phone)
have their voice strained like they are straining to keep their voice level
have their voice "crack with emotion"
have them hesitate before speaking if they're more the type to hold back their anger
if they aren't the type to hold back, an obvious one: have them raise their voice
Hopefully these can help you write your angry characters. Obviously this list isn't exhaustive, as people react to anger - and any other emotion - differently. Truly consider your characters and how they respond to other emotions & situations before picking how your character responds to anger. Thank you and if you have any questions, feel free to send them my way! Happy writing.
