"
You don't hear me when I say,
"Mom, please wake
This line is foreshadowing further into the song when we learn more about the mother. In the second verse we learn that the mother drinks a lot so by Melanie saying "Mom, please wake up", it's implied that the mother has passed out from drinking too much. It also implies that Melanie clearly knows more, or simply just pays more attention to, the problems going on in their family than her mother does.
