I was busy making plans
Like a castle of sand
Never expecting the tide

You were waiting by the shore
Like you'd done so before
Ready to help me to stand

It took me years to see it
Even longer to believe it

Dreams and castles come and go
And still your love is
The only constant thing I know

Life is hard to understand
But you’re holding my hand
And that's all I need to get by

The rest will fall back into place
Like the smile on your face
And my heart will heal in time

It took me years to see it
Even longer to believe it
Many feelings come and go
And still our love is
The only constant thing I know

And it took years for me to see it
And even longer to believe it

Life is changing as we go
And the one thing that I know
Is I'm not scared of growing old
As long as you’re the only
Constant thing I love
