This was an invisible man who wanted to be visible. One day he went to an Eye and Vision clinic.
-Can they make me visible? He asked there.
-I'll put you through to the doctor,” answered the master of reception.
The Eye and Vision doctor had only one eye, but very large, and with a 3D vision. The eye went through the office.
-I can't see it.
-Yeah, of course. That's the problem. I want everyone to be able to see me, including you.
-I understand. Close your eyes.
The invisible obeyed. The doctor lifted a bucket of red paint and threw its contents where she had heard of it. Nothing happened. The paint was left on the floor, staining the office red.
-I am afraid that you, in addition to being invisible, are nonexistent. Or what's usually called a ghost. It's not in the hand to make it visible.
-Not even with a sheet?
The doctor took off her white coat and threw it over her head. The robe fell to the floor and dyed red with the paint that fell.
-Wow!
The invisible man who may have been a ghost or perhaps not, asked depressed:
-What do I owe you?
-A bucket of red paint, a white coat and the cleaning of this office.
The Eye and Vision doctor cannot see him, but the man smiled:
-Phew! It's a good thing that besides being invisible, I'm nonexistent.
And he left. Or maybe not.
