The theme of marriage is presented through the use of metaphors as this provides the poet to have an effective use of imagery throughout the poem. The theme of marriage is present throughout the poem and links back to the name.
Blumenthal has mentioned giving up in his poem to symbolise a broken marriage and how you have to wait for a successful marriage as it has to consist of two individuals willing to help and support one another. The reference to holding up a house and resting your arms whilst the other takes over is a perfect representation and the entire poem provides an image of a house ready to collapse but being held up. An unsuccessful marriage can be seen as someone not willing to hold up the house anymore and leaving one person alone to do it otherwise meaning one person who takes and takes but doesn't give resulting in a broken and unsuccessful relationship.
Blumenthal uses imagery effectively to portray the concept of marriage between two people and the everlasting effects of a bad relationship if you're alone.
