Let it be.  Sit in it.  Like a tree, stand and watch the smallest branch bend in the wind.  Soak up the mist through your hair.  Grab everything you can through your senses.

Watch the crinkle in his eyes as he laughs.  Let her touch to your arm sink in your skin so years after she is gone you remember that soft caring feeling in your body.  Listen to the children in the park squealing, let it wash over you like a fountain of cool water. 

Allow the now to refresh your soul.
