Kleptomania is an illness of the mind that gives a person the desire to steal. Such a person is not really a thief. They are sick and cannot help themselves. All small children act naturally and as they grow up they normally learn to control their actions. People with kleptomania for certain medical reasons have failed to develop control over their desire to take things that do not belong to them. With medical help they may become normal citizens again. The things that a kleptomaniac steals are seldom of great value. They often give away what they have stolen or collect objects without using them. What is the topic of the text?
