How we cite our quotes: (Poem Title, Stanza)
Quote #1
Alone, everything changes […] No mom, Marie, ever more distant in her midlife quest for fame; no stepfather, Scott, stern and heavy-handed with unattainable expectations. (Alone.1-2)
Kristina may live in the same house as her mom and stepfather, but she nonetheless feels abandoned and alone. Her mom is in the midst of a pretty severe midlife crisis, while Scott seems more interested in whom Kristina should be than who she actually is.
Quote #2
I hadn't seen Dad in eight years. No calls. No cards. No presents […] My mom, warrior goddess, threw down the gauntlet when he phoned […] I begged. Pouted. Plotted. Cajoled. I was six again, adoring Daddy. (My Mom Will Tell You.6-8)
Being abandoned by her dad as a child is obviously a major factor in Kristina's unresolved issues—not only does she blame her mom for breaking up their marriage, she seems unable to see her dad's faults. Instead she idealizes him as the person she saw him as when she was a child, no matter how unrealistic this image of him is.
Quote #3
I've been alone since Mom met Scott. He sucked the nectar from her heart like a famished butterfly. No nurture, no nourishment left for Kristina. (Aboard United 1425.5)
Let's try to translate this poetic language. Apparently, Kristina's mom fell pretty hard for Scott and neglected her own kids in favor of emotional involvement with him. As a result, it makes sense that these feelings of abandonment would cause Kristina to resent Scott. Dude took her love away, as far as she's concerned.
