Misunderstandings often happen when two people try to communicate but fail to say exactly what they mean or incorrectly assume that they understand what the other has said. An example of this occurred when a wife asked her husband if he wanted to stop for a drink, since they had been driving in the car for a while, and the wife was feeling thirsty. The husband, thinking his wife was concerned only about his needs, told her that he did not need a drink. Naturally this upset the wife, since she expected him to ask about her needs and wants. In effect, these two different assumptions made it hard for the wife and husband to communicate clearly.
