How would you explain, in your own words, the "old woman's message" in the poem "The Old Woman's Message" by Kumalau Tawali?

The old woman's message is a combination of information and a request: she speaks of how old and frail and thin she's become, and she asks that her sons, Polin and Manuai, return home to see her before she passes away. The old woman feels that her sons have forgotten her, and, in their absence, she has wasted away to practically nothing. Her hands, she says, are "like broomsticks," and her legs can fit into the hole of a very small animal, the sand crab. She sees the sons of other women returning to them, and she grieves, wondering why her sons should be different from theirs. What are her sons thinking in staying away so long? She cannot fathom it. However, as she grows weaker, "sway[ing] like a dry falling leaf," she hopes they will make it in time to be with her when she dies and to attend her wake.
