Exercise 141
In your neighborhood you have frequently noticed a lawn and a garden that are very poorly kept, the garden needing weeding and the lawn both weeding and mowing. Imagine that you go to the owner to make him a proposition. You know the man slightly, and you have heard that he has a quick temper. Know exactly what work you will offer to do and how often you will do it. Be careful of your first sentences. Let them be especially courteous, so that you may not offend the gentleman by suggesting that he does not take care of his property. Tell him frankly that you would like to earn some money.
In this exercise the class will represent the owner. Moreover, they will watch carefully so that they may point out to the speaker wherein his speech was not quite courteous or not quite clear.
