The lamb may lie down with the lion,
But they will never be as close as this pair
Who share the very lines
Of their existence, whose overlapping is their raison d’etre
How strange and symbiotic the binds
That make one disappear
Whenever the other is spied.
Throw the duck a stare,
And the rabbit hops down his hole.
Give the rabbit the eye,
And the duck waddles off the folio.
Say, these could be our mascots, you and I–
I could look at you forever.
And never see the two of us together.
— “Duck/Rabbit”, Billy Collins
