Character Development
Tenses up whenever someone argues with her.
Taps her foot when shes mad
Rolls her eyes when someone she doesn't like is talking
There are a lot more I could give you, but there is just a few!
@Celestial-B Your a great help! (no sarcasm intended. Sorry it just sounded stuck up.)
Naturally loud voice ( level in between crowd control voice and large classroom voice)
Great posture
Resting angry face
