When his heart is growing bitter and his hair is growing grey,
And he hears the debt-collector knocking several times a day,
And the shrill voice of the Missus, blame, reiterate, accuse—
Then the poet who was famous feels inclined to damn the muse— .....

When he hears a sudden rapping—rapping at his chamber door,
Then he knows it's no good trying to write poems any more,
Then he bursts from out his chamber and he grabs his battered hat,
And he cadges Two Bob somewhere and gets beered up on his pat.

Henry Lawson
