That song is about her aborted daughter from Don Henley.

Fleetwood Mac Sara (Lyrics)
Wait a minute baby
Stay with me awhile
Said youd give me light
But you never told me about the fire
Drowning in the sea of love
Where everyone would love to drown
But now its gone
It doesnt matter what for
When you build your house
Then call me home
And he was just like a great dark wing
Within the wings of a storm
I think I had met my match, he was singing
And undoing, and undoing the laces
Undoing the laces
Said Sara, youre the poet in my heart
Never change, never stop
But now its gone
It doesnt matter what for
But when you build your house
Then call me home
Hold on
The night is coming and the starling flew for days
Id stay home at night, all the time
Id go anywhere, anywhere, anywhere
Ask me and Im there, yeah
Ask me and Im there, I care
In the sea of love
Where everyone would love to drown
But now its gone
They say it doesnt matter anymore
When you build your house
Then please call me home
Sara, youre the poet in my heart
Never change, and dont you ever stop
Now its gone
No it doesnt matter anymore
When you build your house
Ill come by
Sara
