You told me that there was, A chasm there between us, I looked and saw it there, And so I built a bridge, With strong foot boards And shiny rails, To stop you falling. I sweep the boards And polish the rails, Most every day. But you didn't come to see, You didn't cross that bridge One day the dust will stay Then you must tread lightly Because some of it will be me. And maybe then you'll cross But you will only find An empty wasteland A desert and my dust Blowing in the wind Unknowable.
