Be ice

Alpha Game:

When your boss yells at you or your girlfriend accuses you of something, don't say anything, don't even allow your face to change expression. Just meet their eyes, breath slowly, and blink deliberately. Then ask them to repeat themselves. Nine times out of ten, they will immediately lower their voice and address you in a calmer, more civilized manner. This is an instinctively submissive response to dominant behavior.

Excellent advice.
