And Then I'll be Your Own

Make me the last thought every night
And the first thought each morn;
Make me the one who comes to mind
when things go fine
And the one you long for
When they go wrong;
Make me the one your eyes search
when you enter a room,
or when you walk down a road
you know I've walked on;
Make me the air that you breathe
and the food you live on;
Make me the soul of your life
And then I'll be your own.
