How does Carol Ann Duffy's 'Mrs Midas' show characters' attempts to deal with life-changing events?

In Carol Ann Duffy's Mrs Midas, the poet is seen to take on the form of a dramatic monologue in order to adequately articulate and express the emotions and experience of the imagined but eponymous persona - Mrs Midas. Taken from her anthology, The World's Wife, Duffy in this poem draws upon the legend of Midas and develops a narrative as a space in which the unheard, silent perspective of female figures and counterparts to male legends, heroes and characters are given free reign to perform and declare their side of the story. In Mrs Midas, the poet distinctly uses an informal, witty style alongside a reflective and retrospective tone to inhabit the persona of a wife who has experienced betrayal and a loss of love with her husband following his wish for the power to turn what he touches into gold, using contradictory language and phrasing to reflect her torn and conflicted state of mind. The opening stanza of Mrs Midas begins by introducing a calm, serene atmosphere in which the near-rhyme of 'poured a glass of wine / begun to unwind' instantly attempts to echo a lulling sense of comfort and security felt by the persona herself, who feels perfectly at home and warmly enclosed in her kitchen personified and 'filled with the smell of itself'. As 'its steamy breath gently blanches the windows', the reader also feels comforted by the continued use of personification - as 'steamy' and 'gently' help to create a particularly cosy and romantic image of the household. However, this is quickly disrupted as we enter the second stanza of the poem and are slowly introduced to the mysterious and dark presence of Midas. In referring to 'the way / the dark of the ground seems to drink the light of the sky', Duffy uses a simile in order to express the very change of mood which has quickly occurred in the poem as reflecting the sudden sense of doom and foreboding - it is suggested that the secure and calm world of the kitchen grows distant as the persona speculates and shows concern about her husband in the garden. For instance, the way in which she proceeds to state of the golden pear that 'it sat in his palm like a lightbulb. On.' invites the reader to join Mrs Midas in her confusion and alertness at something being wrong or amiss. Both the simile and deliberate use of caesura here serve to emphasise Midas' new power as realised but also deliver the importance of this to readers alongside the clear and sudden change in mood, establishing this overall as a catalyst for the poem's action and plot to quickly unravel and thicken.
