For the demonstration of grief:
Beat the breast
Fall to the floor
Wail.
Break the voice into little pieces
Pause
Turn the head away
Hide the eyes in a handkerchief
Sniff and shake the head
Place a black band around the upper arm
Moisten the eyes at the corners with saline
Allow it to drop
Bite the knuckle occasionally
Avert the gaze
Find a hat
Or a veil and
Hide the face
That might reveal the truth.
