* Loss of Innocence: The poem speaks of toys that were once cherished but are now discarded and forgotten. This symbolizes the loss of innocence and the inevitable transition from childhood to adulthood.
* Passage of Time: The poem uses the imagery of toys becoming "old and dusty," highlighting the relentless passage of time. Time, like the toys, erodes the joy and wonder of childhood.
* Ephemeral Nature of Joy: The poem implies that the joy of childhood is fleeting and fragile. Just as toys are replaced with new ones, the carefree days of youth are replaced by the responsibilities of adulthood.
