During my rotation in the endocrinology department, there was a seasoned doctor who specialized in diabetic foot amputations—very sharp and perceptive.

Because he couldn't save the leg, they arranged for the amputated leg to be cremated in advance.
When we were doing rounds, the atmosphere in the ward was so heavy it seemed like water could drip from the air.
He looked at his empty pant leg and suddenly grinned: "Hey, look, I’m the one truly 'walking into the coffin with one leg' now! Haha!"
As soon as he said that, the attending physician and a few senior nurses froze by the bed, their expressions caught between wanting to laugh and feeling that professional decorum wouldn't allow it, making them visibly uncomfortable, only able to stammer and dodge the issue.
At this moment, the newly assigned naive intern couldn’t hold back and burst out laughing: "Haha, master, you’re really funny!"
The seasoned doctor was stunned for a moment, then awkwardly chuckled along.
In that instant, the smell of disinfectant in the ward seemed to fade away.
In the face of heavy ethics, perhaps what’s truly needed is this kind of heartfelt laughter.
