Sunday Morning

No Doubt's 'Sunday Morning' is a song that delves into the themes of personal growth, change, and the shock of seeing someone you thought you knew reveal a different side of themselves. The lyrics, sung by the band's lead vocalist Gwen Stefani, express a sense of betrayal and surprise at the transformation of someone close to her. The song starts with a reflection on the singer's past self, describing her as 'sappy pathetic little me,' indicating a time of vulnerability and perhaps naivety.

As the song progresses, the lyrics suggest a role reversal between the singer and the person she is addressing. The line 'But you looked like me on Sunday' implies that the other person has now taken on the traits that the singer once had, which she no longer identifies with. This change is unexpected, as emphasized by the lines 'You sure have changed since yesterday / Without any warning.' The use of 'Sunday morning' as a metaphor could represent a time of peace and ease, which contrasts with the turmoil brought about by this unexpected change.

The song also touches on the theme of self-awareness and the clarity that comes with it. The singer acknowledges her own growth and change, while also calling out the other person for becoming something she no longer recognizes. The metaphor of trying on someone else's shoes and finding them ill-fitting suggests that the person has attempted to adopt a persona that does not suit them. The realization that the other person is not who they appeared to be is a moment of clarity for the singer, leading to a newfound understanding of herself and the relationship.
