Maud went to College.
Sadie stayed at home.
Sadie scraped life
With a fine-tooth comb.
She didn't leave a tangle in.
Her comb found every strand.
Sadie was one of the livingest chits
In all the land.
Sadie bore two babies
Under her maiden name.
Maud and Ma and Papa
Nearly died of shame.
Everyone but Sadie
Sadie had children out of wedlock, something that would certainly have been frowned upon. However, the fact that there are two babies recalls the two women introduced at the start of the poem, and sets up a parallel.
