This indecision is reflected in the poem's structure. The poem is written in free verse, with no set rhyme scheme or meter. This gives the poem a sense of spontaneity and immediacy, as if the speaker is thinking aloud. The poem also contains many repetitions and hesitations, which further convey the speaker's uncertainty.
The fence itself can be seen as a symbol of the choices that the speaker is facing. On one side of the fence is the familiar and safe world of the past. On the other side is the unknown and potentially dangerous world of the future. The speaker is afraid of what might happen if he climbs over the fence, but he is also drawn to the possibilities that it represents.
Ultimately, the speaker's indecision is left unresolved. He remains standing at the fence, unable to make a decision. This ending reflects the fact that life is often full of difficult choices, and that there is no easy way to know which path is the right one.
In addition to exploring the theme of indecision, "Fence" also touches on the themes of fear, hope, and freedom. The poem is a powerful meditation on the human condition, and it offers a unique perspective on the challenges that we all face.
