When, if ever, is it okay to lie?  Give this some thought.  Be sure that you don't just state your opinion; you have to provide some reasons to convince a reader who doesn't agree.  Concrete examples will help to make your writing more interesting and more convincing.   

You may want to narrow this topic down to a specific situation.  For example, you might want to limit your discussion to when it is okay to lie to your boss or to someone you are in a relationship with. 

There is no required length for this paper, although the average length of papers I've received in the past is between two and three double-spaced pages.  Consider me to be the audience for your paper.
