Insults and Apologies to a Seagull

    By John Sweethardt
    As told by Francis Carlisle

You are structurally unsound.
You wobble on that ferry boat piling on your rickety legs.
What makes you so awkward?
Why are you such a dodder?
brurr brurr brurr brurr brurr brurr
(Ferry boat pulls off)
My apologies to you Mr. Seagull.
Did I say awkward?
I saw no far arching wings.
Did I say rickety legs?
I saw no flit float flutter loll.
Did I say such a word as dodder?
You who can float absolutely atune to the wind.
And wait not quite ready,
Not quite,
Waiting for that long swift plunge to the churned waters.
My apologies to you Mr. Seagull.
I didn't know you.

A magical brew,
An olive in It.
A Kettle.of Fish
With people in it.
Cards and coins and seagulls,
And Francis knows
Wherever you think you see it,
