An albatross is not a duck.
The reason has to do with luck
And quantum physics: Cats can be
Two things at once, not you and me
Or waterfowl. (Don’t I know it,
Else I’d be rich and a poet!)
Waves of shame, regret and loss
Hang heavy on the albatross
That he (or she) a duck is not.
Like us, he must accept his lot
(As she must hers). The Wedding-Guest
Has time; let him explain the rest.
