What is the theme of this poem? One word responses are not valid:

The opera
In her head

Runs with no interval,
A lot of people singing tunelessly

About the same things.
An overheard

Comment like
A rotting peach.

The overzealous
Cockatoo of her impatience,

Flap flap. The slab
Of blue behind her

Is a sea of
Her doubts. The squirrel

In her stomach
Trying to get out—

They say you have to be
Twice as good. They say

There are pills
For everything now. Enamel

Eyes to see all
The better with, my

Dear. Fur coat
For your tongue—
