The poem is a metaphor for love, and relationship; in my opinion it goes through stages of a relationship that most, if not all couples go through, and in order to “build” a strong relationship, you must create strong foundations, as seen in the poem when the poet says to “secure all ladders, tighten bolted joints”. When these scaffolds come down, it finally reveals a wall of “solid stone”; or what I think is a strong relationship, that wont break easily.
