(Bob McDill - Paul Harrison)

One minute she's up, one minute she's down
Lovin' her's like bein' on a merry-go-round
Sometimes she's sad, and sometimes she's funny
Sometimes I wonder if I'm going or coming.

I know she's not easy
To understand
But lovin' her makes me
Do the best that I can.

Chorus:
She's a heart full, unpredictable
Can't explain the things she does
She's a heart full, but she's worth the trouble
'Cause she's got a heart full of love.

--- Instrumental ---

First the sun shines then the rain falls
Sometimes she cries for no reason at all
Then she's a child, restless and moody
Sometimes she looks at me, sometimes she looks through me.

There's things about her
I've never understood
But I wouldn't change her
Even if I could.

Chorus:
She's a heart full, unpredictable
Can't explain the things she does
She's a heart full, but she's worth the trouble
'Cause she's got a heart full of love.

--- Instrumental ---

She's got a heart full of love...
