Perhaps something unexpected like the Monsters Inc. metaphor could help in those screeching situations:
Helpful metaphors dept: The difference between fission and fusion is like the difference between children’s screams and laughter in the movie “Monster’s Inc.” Fission, like screams, is destructive and toxic, but releases a lot of energy. Fusion, like laughter, brings things together and releases much more energy.
Then again, if someone is in screech mode, it’s a lost cause.
