The other day we talked about making sure each character has unique dialogue. What they say and how they say it should be exclusive to each person in your fiction. Similarly, every character should have unique body language. Look around your home or office, what body language do you see? That teenaged girl sighs dramatically and rolls her eyes. That mom can't seem to sit still. That older gentleman shuffles his feet and stares at the ground while he walks. You'd never mix up their body language! Similarly, in your work, strive for unique bodily diction. :)
Does anyone have tips or tricks in this arena?
