The Sea is calling

I am standing at the edge of the sea
Looking at the blue as far as I can see
The waves that are dancing high and low
I watch the water come to me and go

5. I am standing with my feet on the sand
The soft, cold grains still without demands
I feel them sink a little near my toes
How many are there? Nobody knows

I am standing with my fingertips on the water
10. The roaring surfs hum like nothing else matters
As seagulls hover above me, not too high
I hear their call. I, too, want to fly
