what is the poet trying to discover in the poem chidhood?What significant occasions has he mention?

 The poet is trying to discover when he had lost his childish innocence. He's trying to figure out when he had crossed the phase of childhood and wonders if he had lost when he turned 12,or when he realised that not everything in the world is as it appears, when he observed that adults maintained double standards and were hypocrites,or when he had become possessive of things and started thinking independently.
