The song is about the protagonist's emotional turmoil and feelings of betrayal after discovering that her father has been dating someone younger than she initially thought. The protagonist expresses her frustration and disbelief at the situation, as she believed the person her father was dating was thirty years old, but in reality, she is only twenty-eight.
The protagonist questions her father's motives and honesty, suggesting that he intentionally misled her about the woman's age, indicating that he knew it was wrong. She feels hurt and deceived by his actions, believing that there is no excuse for lying to her. The mention of the woman's first high school reunion and being the first person she has ever moved in with implies a significant age gap between the two, further highlighting the protagonist's feelings of discomfort and unease.
The protagonist expresses her desire to forgive, but she realizes that her father never considered the fact that she is still a child and not ready to deal with such complicated situations. She feels burdened by the expectation of being the mature one in their relationship and is tired of crying because of the lies and deceit.
In the chorus, the protagonist reiterates that the woman is only twenty-eight, emphasizing the age difference once again. She sarcastically comments on the justifications given for the relationship, such as the woman being mature, liking sports, and being pretty, asserting that none of these excuses make the age gap acceptable to her.
The protagonist concludes by stating that blocking her father's number is necessary for her well-being. She believes that her father couldn't wait for her to grow older before revealing the truth, indicating a lack of consideration for her emotional readiness. The repetition of the phrase "To tell me she was twenty-eight" emphasizes her disbelief and disappointment in her father's actions, questioning the significance of the age twenty-eight in relation to her own life. The song ends with a defiant and resolute tone, expressing the protagonist's firm stance that no explanation or justification can make the situation acceptable to her.
