What are the main themes present in the short story 'Gemini'?

Here are some themes from the passage:

• Social Class and Inequality: The story highlights the stark contrast between Siva, who serves "affluent businessmen" and is "at the beck and call of sirs and madams," and the wealthy individuals he encounters. His life is on the "periphery" of theirs, emphasizing social stratification.
• Lost Potential and Regret: Siva reflects on his "belated sterile ambitions" to become a doctor or teacher, acknowledging how he "frittered away" his opportunities by neglecting his studies and engaging in distractions. This shows a sense of missed chances and regret.
• Identity and Self-Perception: Siva's internal thoughts reveal his self-awareness of his subservient role and past failures, contrasting with his active imagination. The title "Gemini" might suggest a dual nature or conflicting aspects of his identity.
