This paper illustrates that colloquial languages are used extensively by the modern youths compared to the adults of in their thirties. For example, we can see the intrusions of colloquial languages like apos;s, wanna, gonna etc in spoken English of the current youths. Such colloquial languages are less among the adults in their thirties. In short, the generation gap is widening as time passes. “There always has been generation gap since the dawn of civilization”. “One disturbing poll reveals that only 19 percent attend church regularly. Only 1 percent includes a member of the clergy on their lists of most admired individuals”. Morality and ethics are disappearing from the world rapidly at present. Most of the youths in their twenties or eighties have less interest in religious beliefs which is evident in their activities. Violence and antisocial behaviors are increasing in the world because of the disappearance of ethical values. On the other hand, a majority of the people in their thirties are keener in attending church masses and religious activities. In short, one of the major disadvantages of the generation gap is the loss of values in our social life.
