In things is a broad term that can refer to a variety of different concepts. Rages, FADS, MANIAS, Styles, and TRENDS are all examples of things that can fall under this category. Rages are intense outbursts of emotion, usually anger, that can last for a short period of time. FADS are popular activities or objects that quickly become popular and then fade away just as quickly. MANIAS are intense obsessions with something that can lead to irrational behavior. Styles are the way something is done or presented, often in fashion or art. Finally, TRENDS are the direction something is heading in, often in terms of fashion or technology.
