Ruffiana is a fascinating and somewhat rare word in Italian, literally meaning 'pimp-like' or 'procuress'. It's not a word you hear every day, especially in a romantic context.
In this song, Ligabue uses it metaphorically to describe the moon as 'ruffiana' (con questa luna ruffiana). This gives the moon a mischievous, almost manipulative quality, as if it's enticing or coaxing something to happen, adding a layer of intrigue and personality to the lyrics.
Ligabue sings about using someone (or the memory of them) to clean out his own heart. Under a knowing moon, with the last trace of her scent still on him, he lets an old feeling clear.
The song moves through small, everyday scenes: an April sun that melts old resentment, still having plenty left to learn, running into each other around town. Fear keeps showing up on both sides, hers and his, but neither one lets it stop them from staying close.
The line that keeps coming back, "They called it living," is the song's answer to all of it. Loving someone, getting hurt, forgiving, and carrying on: none of that needs fixing. It is just what living looks like.
