The song "Glycerine - acoustic" by Bush explores themes of love, loss, and self-reflection. The lyrics depict a complex and emotionally charged relationship. The recurring mention of "Glycerine" serves as a metaphor for the emotional vulnerability and fragility within the narrator's connection to someone else.

The opening lines, "Must be your skin that I'm sinking in, Must be for real 'cause now I can feel," suggest that the narrator has become deeply involved with someone, perhaps to the point where their emotions have become intertwined. The following lines, "I didn't mind, It's not my kind, It's not my time to wonder why, Everything's gone white, And everything's grey," convey a sense of confusion and uncertainty. The narrator is unsure about the nature of the relationship and their own emotions.

The chorus, "Don't let the days go by, Glycerin," could be interpreted as a plea for the other person to not let the relationship deteriorate or fade away. The mention of "Glycerin" here signifies a desire to preserve the connection, to keep it emotionally intact.

The lyric, "I'm never alone, I'm alone all the time, Are you at one, Or do you lie," captures a sense of emotional dependency and insecurity. The narrator feels constantly alone even when in the presence of their partner, questioning if the other person truly feels the same depth of emotion.

The verse, "We live in a wheel, Where everyone steals, But when we rise it's like strawberry fields," symbolizes the cyclical nature of relationships and the challenges faced within them. The mention of "strawberry fields" suggests moments of happiness or fleeting bliss despite the difficulties.

The song also touches on the narrator's regrets and attempts at self-improvement. Lines like "Should I have been easier by three, Our old friend fear and you and me" imply a desire to change and make things easier between them, but a struggle with fear and insecurities hinder progress.

The repeated phrase "Glycerine" throughout the song acts as a reminder of vulnerability, the need for emotional transparency, and a plea to maintain the emotional connection despite the challenges faced.

Overall, "Glycerine - acoustic" delves into the complexities of a relationship, the longing for emotional closeness, and the challenges of self-reflection and growth. It captures the raw and vulnerable nature of human connections, encapsulated by the metaphorical use of "Glycerine."
