How do poets present desperation in piano and blessing? Specifically in "Piano" by D.H. Lawrence and "Blessing" by Imitiaz Dharker.

In "Piano" by D.H. Lawrence, the speaker experiences something like desperation, when, against his will, he is pulled by the piano music back into the memories of his past. The phrase at the beginning of stanza two, "In spite of myself," suggests that the speaker tries to resist the pull of the music, but is unable to do so. He wants to resist because the music takes him back to a memory of his mother playing the piano, and this memory causes the speaker pain. The desperation of this pain is indicated by the final words of the poem: "I weep like a child for the past." The simile comparing himself to a child implies that the speaker is reduced to a desperate, helpless state by the oppressive nostalgia of the memory.
In "Blessing" by Imitiaz Dharker, there is a sense of desperation as the people frantically try to capture the water from a burst municipal pipe. Water to these people is a precious resource. They are desperate to take what they can, when they can, because they know that it may be a long time before they get such an opportunity again. Their desperation for water is signaled in the opening line of the poem, with the simile, "The skin cracks like a pod." This simile, and specifically the word "cracks," implies that the skin of these people is parched, and dehydrated. The desperation of the people to capture the water from the burst pipe is suggested by the descriptions of them as they clamor to get their share. There is "a roar of tongues," people "butt in," and grasping hands are "frantic."
