When I saw Must Love Dogs, there were a scene when Sarah's Father, Bill (Christopher Plummer) read a poem from William Butler Yeats. I like that poem, so I start so googling it on net. And here's the poem.
I whispered, 'I am too young,' And then, 'I am old enough'; Wherefore I threw a penny To find out if I might love. 'Go and love, go and love, young man, If the lady be young and fair.' Ah, penny, brown penny, brown penny, I am looped in the loops of her hair. O love is the crooked thing, There is nobody wise enough To find out all that is in it, For he would be thinking of love Till the stars had run away And the shadows eaten the moon. Ah, penny, brown penny, brown penny, One cannot begin it too soon.
