Derry liked to be alone because of a combination of factors, including his burnt face, his inability to bear with people's comments, and his inferiority complex. These factors contributed to his preference for solitude as a means of coping with his personal struggles and finding solace within himself.

1. Burnt face:
Derry's burnt face played a significant role in his desire to be alone. The physical scars on his face made him self-conscious and insecure about his appearance. He may have felt embarrassed or ashamed of his disfigurement, leading him to withdraw from social interactions to avoid potential judgment or ridicule.

2. Inability to bear with people's comments:
Derry's burnt face also made him vulnerable to cruel comments and hurtful remarks from others. These negative experiences likely affected his self-esteem and emotional well-being, making it difficult for him to handle the opinions or reactions of people around him. As a result, he chose to isolate himself to protect his emotions from further harm.

3. Inferiority complex:
Derry's burnt face and the reactions it elicited from others may have contributed to the development of an inferiority complex. He may have felt inferior or unworthy due to his appearance, leading him to believe that he would never be accepted or valued by society. This sense of inferiority could have further reinforced his inclination for solitude, as he may have believed that being alone was better than facing rejection or feeling inadequate in the presence of others.

In summary, Derry's preference for being alone was influenced by the physical and emotional challenges he faced due to his burnt face. His desire to avoid judgment, protect his emotions, and cope with his feelings of inferiority led him to seek solace in solitude. It is important to note that each individual's reasons for preferring solitude may vary, and in Derry's case, it was a combination of his physical appearance and psychological struggles that contributed to his inclination for being alone.
