Meaning of How strange that I don't know you at all

In Taylor Swift's song "Come Back... Be Here," the overall theme centers around the longing and yearning for someone who is physically absent. The lyrics express feelings of missing someone and the difficulties of being apart from them. Each verse presents a different aspect of this longing, with the line "How strange that I don't know you at all" standing out as a particularly poignant and thought-provoking expression.At first glance, the line may seem contradictory or confusing. How can someone not know someone at all, yet long for their presence? However, when viewed through a creative and imaginative lens, this line reveals deeper themes that contribute to the overall message of the song.One theme that emerges is the idea of misplaced familiarity. Sometimes, we may find ourselves drawn to someone we barely know, feeling a connection that defies logic or explanation. It's as if our souls recognize each other from another time or place, even though our conscious minds cannot comprehend it. The line suggests that despite not truly knowing this person, there is an unexplained sense of familiarity that heightens the longing to be with them.Another theme that arises is the bittersweet nature of love and longing. Love has a way of sneaking up on us when we least expect it, catching us off guard and leaving us yearning for something that feels almost elusive. In the context of the song, the line implies that although there is a strong desire to be together, there is also a sense of loss and confusion, emphasizing the complex and contradictory emotions associated with love and longing.Furthermore, the line alludes to the transient nature of relationships and the uncertainty that accompanies them. Relationships can be unpredictable, and we often never truly know the depth of a person until we spend more time with them. The use of the word "strange" highlights this sense of unfamiliarity, serving as a reminder that even though we may feel a deep connection, there is still much to discover about the other person.Overall, the theme encapsulated in the line "How strange that I don't know you at all" invites listeners to explore the mysterious and wistful aspects of love and longing. It encourages us to reflect on the complexities of human connections, acknowledging that sometimes we can yearn for someone we barely know and long for a deeper understanding of their essence. Ultimately, the line adds depth and nuance to the song's overarching theme of missing someone and the emotional turmoil it brings.
