When you are with me I put by the world
In having you. When I can hear and see you,
All else is dark and dumb; or is it, Sweet,
You then are all, and I the dreamer know
No life but yours? But when that you are gone,
All things do image you, they do live then
For me, and in a thousand lights and shadows
A thousand voices echo you, until
Your presence dumbs and darkens them again:
Love has so made you, dearest, one with all
In and without me.

Robert Crawford
