Introduction:
The poet believes that adults are hypocrites. This means that they often say or preach one thing but do something completely different. In this answer, we will explore the reasons behind this belief and provide examples to support the poet's perspective.

Adults often say one thing but do another:
One reason why the poet believes that adults are hypocrites is because they frequently say one thing but do another. They may preach about the importance of honesty, yet lie in their own lives. For example, an adult may tell a child to always be truthful, but then they themselves may lie to their boss or spouse. This inconsistency between their words and actions is a clear indication of hypocrisy.

Adults have double standards:
Another reason for the poet's belief is that adults often have double standards. They hold different expectations for themselves compared to others, especially children. For instance, an adult may demand respect from a child but not show the same level of respect towards them. This double standard demonstrates a lack of integrity and reinforces the idea of adults being hypocritical.

Adults often hide their true intentions:
Furthermore, adults are often cunning in their approach to situations. They may pretend to have good intentions but actually have hidden agendas. This deceitful behavior contributes to the perception of adults as hypocrites. For instance, an adult may appear to be caring and concerned, but their true intention may be to manipulate or control others for their own benefit.

Conclusion:
In conclusion, the poet's belief that adults are hypocrites is supported by their tendency to say one thing but do another, their use of double standards, and their ability to hide their true intentions. These characteristics are often observed in adults and contribute to the poet's negative perception of them. It is important to note that not all adults exhibit hypocritical behavior, but the poet's perspective highlights a common observation in society.
