You said that I

You said that I "was Great"-one Day-
Then "Great" it be-if that please Thee-
Or Small-or any size at all-
Nay-I'm the size suit Thee-

Tall-like the Stag-would that?
Or lower-like the Wren-
Or other heights of Other Ones
I've seen?

Tell which-it's dull to guess-
And I must be Rhinoceros
Or Mouse-
At once-for Thee-

So say-if Queen it be-
Or Page-please Thee-
I'm that-or nought-
Or other thing-if other thing there be-
With just this Stipulus-
I suit Thee-
