In the World by Maksim Gorky

I went out into the world as “shop-boy” at a fashionable boot-shop in the main street of the town. My master was a small, round man. He had a brown, rugged face, green teeth, and watery, mud-colored eyes. At first I thought he was blind, and to see if my supposition was correct, I made a grimace.

“Don’t pull your face about!” he said to me gently, but sternly. The thought that those dull eyes could see me was unpleasant, and I did not want to believe that this was the case. Was it not more than probable that he had guessed I was making grimaces?
