If one only had something to eat, just a little, on such a clear day! The mood of the gay morning overwhelmed me, I became unusually serene, and started to hum for pure joy and for no particular reason. In front of a butcher's shop there was a woman with a basket on her arm, debating about some sausage for dinner; as I went past, she looked up at me. She had only a single tooth in the lower jaw. In the nervous and excitable state I was on, her face made an instant and revolting impression on me - the long yellow tooth looked like a finger sticking out of her jaw, and as she turned toward me, her eyes wee full of sausage. I lost my appetite instantly, and felt nauseated.
