Life is full of misunderstandings.
Think of some situations in which you have witnessed misunderstandings. They may have occurred at work, at home, or in some extra curricular activity. See if you can devise categories for these misunderstandings. You may have heard, for example, that all New Yorkers are rude, all Westerners love the great outdoors, all Newfoundlanders tell funny stories. If you happen to be from any of these places, you know for a fact that the people come in dozens of varieties.
