While taking washing off the line, I hear my neighbour (who until today I'd only heard shouting at her sons) singing a few lines from an old song rather beautifully. I pause, trying to keep as quiet as possible, and wait until she finishes. I don't manage to record her but I find the words later - they were originally sung by Carlos Gardel.
El día que me quieras
La rosa que engalana, se vestirá de fiesta con su mejor color
On the day that you love me
The pretty rose will dress in its best colour in celebration
