Aside from water, soap is the most basic element of cleanliness. It is significant that soap is one of the first things taken from the natives in No Sugar. An unclean child cannot attend school. A child who is not in school cannot learn. An unclean body is more likely to contract and spread germs and disease. A diseased body can be relocated with the stroke of a government official’s pen.

Each time Billy’s whip appears, the playwright uses it to make a startling point. A whip has little practical value unless being used as an object of coercion. Anyone who wields it acts in the service of making others follow orders.
