How to make a bed

My sisters, who are identical twins, were given an assignment in school to write an essay telling "How to make a bed." The first twin's essay was very well written, "First you put on the bottom sheet, then the top sheet,...etc." The second twin's essay was also well written, "First you get your parents' permission, then you get some wood and nails and a hammer..." They both described how to "make" a bed, they just interpreted the word differently.
