"but that twig in his hand was gold," this shows the first visibility of his wife realising that his 'gold touch'. Using the word 'but' contains uncertainty about what is happening
Mrs Midas by Carol Ann Duffy
"Corn on the cob. Within seconds he was spitting out teeth of the rich," this uses the corn and turns it into a human feature, as the corn once turned into gold looks like the shape of teeth, as well as it also coming out of his mouth. Using the word 'rich' refers to it turning into gold.
"I made him sit on the other side of the room and keep his hands to himself," this is where she begins to become scared of him, this is implied through her making him sit on the other side of the room as if she wasn't scared she would want more for his embrace then for him to be on the other side of the room.
"I feared his honeyed embrace, the kiss that would turn my lips into a work of art," she began to be scared to go near him and do talks about being turned into a 'work of art' talking about the way she will be turned into gold but also brings out a narcissistic side to her.
"And then I came home, the woman who married the fool who wished for gold," as his wish was affecting her she took an action of making him leave. She was angry as she describes her husband as a fool and does not show any love or sympathy for him, realising that their marriage was a mistake.
"What gets me now is not the idiocy or greed but lack of thought for me," this shows a more self absorbed side of her but also a sad side making the reader feel almost sympathetic for her. She seems to be upset for him not having a thought about her and this could be due to something such as a bad relationship or her not feeling as if he was very committed.
