If we take this bird in, with it's broken leg,
We could nurse it, she said,
Come inside for a little lie down with me,
And if you fall asleep, it wouldn't be the worst thing.
But when I wake up, and your make up is on my shoulder,
And tell me if I lie down, would you stay now?
Let me hold ya, oh
I see it as the little bird being a metaphor for their relationship. When it gets a bit broken, she's the one who tries to fix it. She wants to make it better.
