What does 'but their eyes are mine' (line 11) in the old woman's message (kumalau tawali) mean?

Stick these words in your hair

And take them to Polin and Manuai

my sons:

the ripe fruit falls and returns

5 to the trunk – its mother.

But my sons, forgetful of me,

are like fruit borne by birds.

I see the sons of other women

returning. What is in their minds?

10 Let them keep the price of their labour

but their eyes are mine.

I have little breath left

to wait for them.

I am returning to childhood.

15 My stomach goes to my back

my hands are like broom sticks,

my legs can fit in the sand crab’s hole.

I am dry like a carved image

only my head is God’s.

20 Already I sway like a dry falling leaf

I see with my hands –

oh tell Polin and Manuai to hurry

and come to my death feast.
