Try a cliche...

What is a cliché? It can be defined as an expression or idea that is characterized by its overuse. We generally know it is a cliché when we can tell the sentence or how the situation will end. Examples of clichés (sentences) are “What goes around comes around” or “the writing on the wall.

 Clichés become overused through the fact that there are used by everybody and even broadcasted through the media. Clichés are represented in the media through different outlets: movies, series, and magazines. They become stereotypes.
We often see on TV clichés of men or women. Men (the player; the divorced men or the nerd) or women (the housewives, the 40 year old single women or independent business women.
We apply what we see on TV; we try clichés on a daily basis (for example men who are player) .TV “sets a norm” that we want to comply with. It is important in life to set our standards ; be ourselves and not just follow the crowd.
