The four imaginary characters depicted in this story --
the mice: "Sniff" and "Scurry", and the little people: "Hem" and "Haw" --
are intended to represent the simple and the complex parts of ourselves, regardless of our age, gender, race, or nationality.

Sometimes we may act like

Sniff
Who sniffs out change early, or
Scurry
Who scurries into action, or
Hem
Who denies and resists change as he fears it will lead to something worse, or
Haw
Who learns to adapt in time when he sees changing leads to something better!
