The song "Don't I Know It" by Gilbert O'Sullivan tells the story of a person who realizes they took their lover for granted and is now facing the consequences of their actions. The lyrics convey the regret and realization of the protagonist, as they repeatedly question themselves with the lines "Don't I know it, how you don't love me girl" and "Don't I know it, how you don't want me girl." The protagonist acknowledges their mistake of not appreciating the love they received and admits that they should have put more effort into the relationship. They now find themselves suffering the consequences of their actions, as they see that their lover no longer wants them. The chorus emphasizes the protagonist's awareness of the situation, repeatedly asking the question "Don't I know it?" This demonstrates their understanding of the reality they face, that their lover does not love them anymore. In the second verse, the protagonist tries to convince themselves that it doesn't matter and that they don't care, but deep down, they cannot deny the truth. They realize they cannot live without their lover and feel their absence when they're not around. The song also touches upon the idea that the protagonist had opportunities to make things right but failed to do so. Despite the possibility of arguing that it's not entirely their fault, they admit they got things wrong in the end. Overall, "Don't I Know It" portrays the regret, self-reflection, and longing of someone who realizes the value of their lover after it's too late. The song serves as a reminder to appreciate the love we have and not take it for granted.
