Infidelity, romantic betrayal, mild physical intimacy reference

Detailed Analysis

This song, 'What You Did Last Summer' by Shawn Mendes and Camila Cabello, deals with themes of infidelity, betrayal, and relationship breakdown. The lyrics describe one partner discovering the other has been unfaithful ('Another's hands have touched my skin'), lies within a romantic relationship, emotional pain from deception, and the struggle to let go of a failing relationship. There is no explicit profanity, graphic violence, or direct drug/alcohol references. However, the reference to physical intimacy with another person ('Another's hands have touched my skin') constitutes a mild sexual undertone related to infidelity. The emotional weight of betrayal, deception, and a deteriorating relationship makes this more suitable for teenagers than younger children. The themes of guilt, dishonesty, and romantic betrayal are mature but handled in a relatively restrained and emotionally honest way.

Lyrics

Ah-ah, hey-hey Ah-ah, ah-ah Ah-ah, hey-hey Ah-ah, ah-ah He knows Dirty secrets that I keep Does he know it's killing me? He knows, he knows D-d-does he know Another's hands have touched my skin? I won't tell him where I've been He knows, he knows, he knows It's tearing me apart She's slipping away (I'm slipping away) Am I just hanging on to all the words she used to say? The pictures on her phone She's not coming home (I'm not coming home) Coming home, coming home I know what you did last summer (ah-ah) Just lied to me, "There's no other" (hey-hey) I know what you did last summer Tell me where you've been I know what you did last summer (ah-ah) Look me in the eyes, my lover (hey-hey) I know what you did last summer Tell me where you've been I know, I know, I know, I know (ah-ah) I know, I know, I know (hey-hey) I know, I know, I know, I know (ah-ah) I know, I know, I know (ah-ah) I didn't mean it, no (ah-ah), I didn't mean it, mean it, no (hey-hey) Can't seem to let you go (ah-ah) Can't seem to hold you close (ah-ah) I know When she looks me in the eyes They don't seem as bright No more, no more I know That she loved me at one time Would have promised her that night Cross my heart and hope to die It's tearing me apart (it's tearing me apart) She's slipping away (I'm slipping away) Am I just hanging on to all the words she used to say?
