Bobos is a colloquial term for minor aches, pains, or injuries, similar to "boo-boos" in English. It's an interesting word because it's informal and often used in a tender or slightly childish context.
In the song, the lyric "Quand c'est trop tard, c'est la raison qui soigne tous les bobos" (When it's too late, it's reason that heals all the boo-boos) uses bobos metaphorically. It refers to the emotional hurts and wounds caused by following one's heart blindly, which reason then has to mend.
Have you ever been torn between following your heart and listening to your head? In "Le Coeur Ou La Raison," which means "The Heart or The Reason," Lynda perfectly captures this classic internal battle.
She describes her heart as a hopeless romantic, diving headfirst into love like a character in a movie. It's impulsive, blind to flaws, and forgets all past pain. But this often leads to heartbreak. On the other side is her reason, the logical and protective voice in her head. It's cautious, always thinking about the future, and tries to shield her heart from getting hurt again. The song is all about the painful struggle of being caught in the middle, unable to choose which path to take. It’s a powerful anthem for anyone who has ever felt that difficult pull between passion and practicality.
