1 I followed every rule the garden gave,
2 the stake, the string, the pruning at the node;
3 unless — the wild vine crossed my ordered path,
4 and taught the gate another way to load.
The abrupt stress and pause on 'unless' interrupts a list of orderly actions. How does the metrical break signal the poem's turn?
