Reality is the way things actually are, not the way you might want them to be. Many TV shows claim to be reality, but they are really just pretend. The only actual reality is the life that happens every day.
The noun reality harkens back to the late Latin realis, and later to the mid-16th Century Medieval Latin reālitās, referring to legal property matters, with the current meaning of "true existence" not coming about until 1647. Philosophers and scientists often debate about the true nature of reality, and a common philosophy is that a person’s reality is whatever he or she thinks it is. Or, as film director Tim Burton once said, "One person's craziness is another person's reality."
