what was wrong with derry's face?what did he think of it?
Derry's face was disfigured when accidentally acid fell on his face. His face was frightening to look at and this made the onlookers recoil on seeing Derry. However, unlike Mr. Lamb, Derry was unable to take this disfiguration in his stride. He provided too much importance to the manner in which people behaved on perceiving his face.
"It ate my face up. It ate me up' say Derry to the old man." These lines refer to the acid, which burnt the face of Derry. He says that the acid not only burnt his face, it burnt and killed his self-confidence and self-esteem as well. All this reflected in Derry's attitude. He became a pessimist and did not like to interact with others. He liked to stay alone due to which he had gone to the garden, which he thought was a secluded place. Moreover, when Mr Lamb tried to be friendly with him, he rudely asked him not to hide the feeling of awkwardness on seeing his face.
