"Now," She closes her eyes and when she opens them they return to the pretty purple that I admire, her facial features cool down and she looks passive, emotionless would be the right word. "Take your seat and listen carefully to what I will say next and think very carefully even more so than you did while listening, think before you open your mouth if not I will do to you what you would regret and I can swear on my mother's grave that you will wish you had never been born." She said all this quite calmly as she takes her seat.
I stand corrected this is scarier, no! Deadly is the right word to describe it. She should shout than speak calmly. You know what they say, 'The calm before the storm.'
