Analysis of The Pillar Box

The pillar box is fat and red,
The pillar box is high;
It has the flattest sort of head
And not a nose or eye,
But just one open nigger mouth
That grins when I go by.

The pillar box is very round
But hungry all the day;
Although it doesn't make a sound,
Folks know it wants to say,
"Give me some letter sandwiches
To pass the time away."

"A postage stamp I like to eat
Or gummy letterette."
I see the people on the street,
If it is fine or wet,
Give something to the greedy thing;
They never quite forget.

The pillar box is quite a friend;
When Father goes away
My Mother has such lots to send,
Far letters every day,
And so I drop them in its mouth
When I go out to play.
