Easy to define it as a beautiful or sad or moving song.
It is only a precise, trait by trait, image of relation, parenthood, promises, illusions. A simple story, so often present in near reality, cold, brutal but good kick for discover the life in its pure nakedness.
Sinead O Connor sings about her , you know very well that. But exactly this detail matters because scene by scene, it becomes an universal story , easy recognizing slices from your or closed one life.
A song about be parent.
To hope the other remains near you.
About children as the most precious good thing of your life.
And about a gentle form of sadness as honest answer to every new challenge.
