From the 'Skirrid Hill' collection
The water torture of your heels
emptying before me down that Paris street,
evacuated as the channels of our hearts.
That will be one memory.
The swing of the tassels on your skirt
each step filling out the curve of your hip;
your wet lashes, the loss of everything we'd learnt.
This is the first of three  refrains  which give the poem its structure — terse lines that deliberately interrupt the flow of free verse. 
 It suggests that the relationship is potentially over. 
 Refrains are usually grammatically identical or at least similar. Here, the phrase ‘That will be’ is repeated, using the technique of  syntactic parallels  to achieve rhythm and emphasis.
