Stanzas six to eight

Kay's son has travelled from Arctic conditions to a subtropical climate, suggesting the sheer scale of his adventure.

The grandfather warns once again of conflict in Bolivia - suggesting the (grand)parental urge to protect. But Kay's son is drawn to the open space of the salt-flats and natural world of the rainforest. The list of experiences and countries creates the impression of a young man who is looking to expand his world. This contrasts with the earlier images of his protective containment at the beginning of the poem.

quote
And now you are not coming home till four weeks after / your due date.

Kay’s slightly exasperate tone conveys her disappointment that she will have to wait longer for her son’s return. The expression due date takes us back to the expectant mother at the beginning. Once again she can do nothing but wait for her son.
