In what ways does Heaney vividly convey feelings of disappointment in "Blackberry-Picking"?

the second stanza described how the blackberries have not turned out the way Heaney wanted them to turn out. The fact that Heaney uses a shorter stanza describing the "sour" blackberries implies to the reader that that Heaney does not want to dwell into his disappointment. It's almost as though this experience is too sad for Heaney to talk about in too much depth. This, therefore, emphasises the point of how disappointed Heaney is.The clever use of vocabulary is another way in which Heaney vividly describes his disappointment. At the start of the second stanza, Heaney uses the word "hoarded." Hoarded could also refer to jewellery or coins. This, therefore, makes the blackberries sound as though they are very valuable to Heaney. Whenever we lose something important to us, we tend to feel an immense feeling of disappointment. Therefore, by using this word, Heaney is making it sound as though he has lost something very valuable to him. This undoubtedly would have led him to feeling very disappointed.Heaney's use of half-rhyme towards the end of the poem is another very clever technique used by the poet to convey his feelings of disappointment. In the second stanza, Heaney uses the half-rhyming words "cache" and "bush." The use of half-rhyme rather than full-rhyme is important as it makes us feel as though the rhyme is not complete. This gives us a sense of unsatisfaction. Perhaps Heaney wanted to give us a sense of unsatisfaction so that we could feel the unsatisfaction and disappointment that Heaney feels. This, therefore, invokes sympathy from the reader and makes it easier to understand and sympathise with Heaney's disappointment.The slightly obscene way in which Heaney describes the blackberries in the first stanza also makes Heaney's disappointment more clear. Heaney says that the blackberry juice leaves "stains upon the tongue and lust for/ Picking." The words "tongue", "stain" and "lust" could be seen as words which are used to imply something sexual. Sex can be seen as very satisfying for people, so perhaps Heaney uses the sexual references to show just how satisfied he was while picking the blackberries. However, incomplete sexual encouters can lead to immense unsatisfaction. The fact that Heaney's blackberry picking experience is therefore, in a way, not complete could be linked to the disappointment of uncoplete sexual encouters. The use of obscene ways in describing the blackberries, therefore, is a very clever technique used by Heaney to vividly convey feelings of disappointment.In Blackberry-Picking, Heaney's clever use of poetic and descriptive devices are very powerful techniques used to describe Heaney's disappointment. All of the techniques used make the reader, like Heaney, think that picking blackberries "wasn't fair."
