Percy, Waiting For Ricky by Mary Oliver

Your friend is coming, I say 
to Percy and name a name

and he runs to the door, his
wide mouth in its laugh-shape,

and waves, since he has one, his tail.
Emerson, I am trying to live, 

as you said we must, the examined life.
But there are days I wish  

there was less in my head to examine,
not to speak of the busy heart.  How

would it be to be Percy, I wonder, not
thinking, not weighting anything, just running forward.
