The riddle invites sharing with friends or family members. Observation of responses can reveal how many encounter the common early calculation.
The process of working through the riddle begins with the initial reading. The mind forms an immediate picture of the family. Nine sons appear clearly. The sister reference follows. The impulse to multiply arises from the word “each.”
