I thought of you and how you love this beauty,
And walking up the long beach all alone 
I heard the waves breaking in measured thunder
As you and I once heard their monotone.

Around me were the echoing dunes, beyond me
The cold and sparkling silver of the sea —
We two will pass through death and ages lengthen
Before you hear that sound again with me.

 

Here is a poem by Sara Teasdale, whose work never fails to touch me with its simplicity and its beauty. This is, of course, a very sad poem, because it evokes a love that is in many ways impossible (the lovers will never meet again in this life). I think it delivers an incredibly true sense of what it is to be separated from the one you love, and describes so beautifully the simplicity of what it is we need or miss
