"In Theory" is a song by Kina Grannis that reflects on the contrast between sounding wise and rational with words, while experiencing internal turmoil and emotional pain. The lyrics suggest that the speaker often presents themselves as knowledgeable and wise, sharing theories and ideas that sound rational. However, behind the façade of wisdom, their eyes reveal their true emotions, as they are crying. The song highlights the limitation of words and theories in controlling various aspects of life. The speaker describes feeling bound up and shackled whenever they try to run, implying that their own mind holds them back. When they are lost, it is due to their own choices and intentions, resulting in them being left behind. This suggests that the speaker may struggle with self-imposed limitations and the consequences of their decisions. Reflecting on their childhood, the speaker shares that they used to view the future as a game, something to be played with ease. However, as time has passed and realities have set in, they are now learning that life is not as simple as it once seemed. This can imply that the speaker has faced challenges and hardships that have changed their perspective. The lyrics also touch upon experiencing the end of something and witnessing friends moving on, bringing real fear and the understanding of what it truly means to cry. This suggests that the speaker has gone through significant losses and emotional pain in their life. The song concludes with the speaker reaching out for love, expressing their longing for connection and emotional support. The repetition of "Reach out for love" emphasizes their desire for comfort and understanding. Overall, "In Theory" explores the dichotomy between outward appearances and internal struggles, highlighting the limitations of theories and words in controlling emotions and life experiences.
