A Fishy Tale

They always say the fish they caught
Last year were twice the size,
And make a big production of
Their rods and lures and flies.
They tell the tallest tales, it seems,
Straight-faced and without blinking:
It's not exactly lies, you know,
But rather fishful thinking.

—Harriet Cooper

The wishful thinker often ends up being in a wistful condition.
