Rogers answered this question by saying that the reality of a person's environment is how he or she perceives that environment. And one's perception may not coincide with objective reality. We know that we may perceive some aspect of reality far differently from the way someone else does. You may look upon the behavior of another college student in a dramatically different light than does your 70 year old grandmother or grandfather. Also, ous perception can change with time and circumstances. Your own perception of a college student’s behavior may change drastically by the time you are 70.
