Not all that long ago, I watched a surgeon publicly dress down a young registrar for writing up a bag of magnesium for a post-op patient who was — would you believe — low in magnesium.

She just stood there and took it. 

There was a lot of swearing and aggression, arms were flailing, and there was a shower of saliva for anyone who happened to be too close. 

But she did not flinch. She did not cry. She stood with an air of resilience, but when it was all over and people had lost interest in the show, you could tell he had broken her.
