The world has grown too big,
The firmament too wide:
I could lose you in a moment
Like a leaf borne on the tide,
Like a swallow on a cloudy day,
Like a feather in the storm,
Like a flame that's fading in the grate
Though I'm longing to be warm.
Leaf, come drifting back to me
Like some miracle of fate;
Swallow, turn and fly my way -
By autumn, it's too late;
Feather, blow against my face -
I'll feel your touch at night;
Flame, rekindle in my hearth -
There is no other light.
Giles Watson
