Estranhos translates to "strangers". It's an interesting word because it captures a sense of distance and unfamiliarity, which is a central theme in the song.
The lyrics state, "Tanto faz / Estranhos / Tão iguais" (It doesn't matter / Strangers / So alike). This juxtaposition of being strangers yet so similar creates a poignant image of a relationship that has become distant, despite a shared past. It's a word that evokes curiosity about the nature of this lost connection.
Capital Inicial wrote "Não Me Olhe Assim" as a plea, not a complaint. The singer isn't asking for love back, just for the other person to stop performing pity: "Não me olhe assim" [Don't look at me like that], "Não me queira mal" [Don't wish me ill]. Being treated like a stranger turns out to be easier than being treated like an ex, and the song sits inside that discomfort instead of trying to resolve it.
The sharpest image lands halfway through: "Como um barco perdido no mar" [Like a boat lost at sea]. That line does the work of describing a whole relationship adrift, with neither person steering anymore, right after the singer admits "Não me deixe só" [Don't leave me alone]. Still, the song doesn't stay in the dark. "Se esse for o fim" [If this is the end], it says, "Sempre vai haver" [there will always be], "Uma luz que não vai apagar" [a light that won't go out], a small, stubborn hope tucked inside a breakup song that never pretends the wreck isn't real.
