You used to sing always:
When you bathed your timid skin,
When you dusted your tiny hours.
You said: life should be a song
To sooth our silences.
Sister. Your life was a song:
A canticle as old as love.
As old as sadness.

Background: the sister who loved singing. The canticle of love alludes to the "Canticle of Canticles" in the Bible.
