The finger picking pattern is up to you to figure out.
I don't know how to explain it well enough.
That's the key, though.
Let your ears teach your fingers
Just like they taught your tongue how to talk
Little bird come and sit upon my window sill.
He sat there thru the falling rain.
As I watched that little bird upon my window sill
I saw my thoughts of you go by again
And the picture of my face reflected on the pane
Is it tears I see, or is it rain?
I remember how we talked before we said goodbye
Too young to know the world outside our door
We laughed and said that love was free
Like birds that fly the winds
And the rain today day made me think of you once more
I've no regrets about the past I see how young we were
When the world was love and life was but a thought
But many things go many ways and many times but once
Till your life is past and your love is but a thought
As my thoughts go tumbling back I wonder how you look
I wonder if you've seen that little bird
I wonder if he's sat upon your window sill
And I wonder if you'll ever hear these words
