can we float

A mermaid found a swimming lad,
Picked him for her own,
Pressed her body to his body,
Laughed; and plunging down
Forgot in cruel happiness
That even lovers drown.

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.
