Once I was undergoing an examination in the military department, and in the office of the ophthalmologist doctors. I was shown pictures, allegedly a test for daltonism:
Q. What do you see here?
and I. The triangle.
Q. And what one?
and I. Downward downward down.
You are not ashamed, young man.
and I. For what?
No one has ever lowered a triangle like this before you.
