The specific differences in organization

Imagine that you are the head of the Public Safety Department at your college. Faculty and staff have been parking illegally, sometimes where there aren’t parking spots. Sometimes the individuals without handicaps are parking in spots reserved for those with handicaps. Write two memos to all college employees announcing that, beginning next week, the Public Safety Department will be strictly enforcing parking rules–something it hasn’t been doing. Write the first memo in a friendly voice and the second in a stern voice. Then compare the specific differences in organization, sentence structure, word choice, and other features of writing to create each voice.
