One in a fifty million chance:
A mother with two wombs,
One double crib;
Within,
Twin, twin,
Both sole and sib,
Fed in adjoining rooms
Until their final severance,

Which also means deliverance.
Two lately-hidden blooms,
Each its own soul,
Bones, skin,
But kin,
One half, one whole,
Or as the world assumes
One in a fifty million chance.
