That Sinking Feeling
I was using it this morning to test the vision of an older patient, who started reading confidently at the top, only to stop abruptly after 'X-U-A'.

When she failed to continue, I asked her "Can you see anything below that?"

She replied "Yes."

I said "What?"

She said "A sink."

The same word accurately describes what my heart did. I wouldn't mind, but she was deadly serious.
