I'd like to make a start. The Simon Armitage pdf has 3 poems and some suggested questions. Does anyone have any idea what the second one means (the question, not the poem)? Does the name Damien have special significance?
Damien wants to keep the snowball intact so that he can play a childish joke. The 'housewife' has been taking little bits for various uses, until it's all gone. The uses are all connected to being a housewife, but they're totally implausible. It would be possible to use bits of frozen snow to make an ice pack (though frozen peas would be better), but no one would use dirty snow for any of the other uses, especially when they already own a chest freezer! Presumably Damien never opens the freezer - cooking is her job - but has he really not noticed his wife's gone until it's time for his annual prank?
I suspect I'm not meant to notice these things, but to find some deep metaphorical meaning instead. Perhaps the 'true scald of Antarctica's breath' is the love there should be between them, but for him it's just something from the past, preserved but never looked at, and hers has dribbled away in domestic duties.
What does anyone else think?
