Mafalda's "Shivers" is about a physical reaction the speaker can't quite control, and the mixed feelings that come with it. The shivers run down her spine just from thinking about someone, and she admits they point to something, "just maybe not what I want." That line carries the tension: her body is telling her one thing while her mind wants another.
The second stanza looks back to a single moment, the time "you kissed me." She says she liked the shivers, but the last line undercuts that with "I hated that I liked them." The speaker seems annoyed at herself for being drawn to someone she doesn't want to be drawn to, though the poem doesn't say why.
The mood is quiet, honest, and a little frustrated. The short, plain lines and the repeated "at least" make it sound like she is half defending herself, trying to hold on to one good memory while still feeling uneasy about it.
