Use the poem to answer the question.

The metaphor in the poem compares the speaker's thoughts to a "hum of bees." This suggests that their thoughts are busy, active, and perhaps somewhat chaotic, similar to how bees flit around flowers. The mention of bumble-bees moving around the petals indicates that these thoughts are not only numerous but also engaged in a process of exploration or discovery. This metaphor evokes a sense of restlessness and creativity, as bees are often associated with pollination and the transfer of ideas or energy. Overall, it conveys a lively and dynamic mental state.
