Reproche translates to 'reproach' or 'scolding'. It's a powerful word that goes beyond a simple complaint, implying a more formal expression of disappointment or accusation.
In this dramatic song, the singer declares she's tired of hearing "el mismo reproche cada día" (the same reproach every day). This single word captures the exhausting, repetitive nature of the arguments that finally push her to leave.
Pimpinela, an Argentinian brother-sister duo, are famous for their unique style: they turn dramatic arguments between a couple into pop songs. "Estoy Cansada" is a perfect example of what they do best. The song opens with the woman declaring she's leaving. She's completely over it, telling her partner, "Tú sigue tu camino / Que el mío empieza hoy" (You go your way / Mine starts today).
He seems surprised, but she's not having it. She's tired of feeling like a "esclava de tu incomprensión" (slave to your incomprehension) and sick of his constant complaints, the "mismo reproche cada día" (same complaint every day). The song builds from her being "cansada" (tired) and "herida" (hurt) to being straight-up "furiosa" (furious). The final line is a brilliant parting shot. After saying she's tired of listening to him, she adds, "tal vez alguien lo quiera hacer por ti" (maybe someone else will want to do it for you). It's a theatrical, satisfying end to a relationship that has clearly run its course.
