peer pressure

Rivalry is common among teenagers because at this point of time young boys and girls develop the insecurity thing, they feel inferiority among their friends or the other way around, feeling superior over others and this causes the rival.Teens having lower self-esteem become pretenders just to suit themselves with their friends, they forget to show up the real them that's why instead of boosting up their personality they just let others' identity conquer them which won't bring them any good. They may also be puppets of those who feels superior over them.

On the other hand, those who feels superior are those youngsters full of pride as if they were the greatest, prettiest and smartest that leads them to insult others and to hurt someone else, emotionally and even physically. They think they're gods and goddesses who have power over the others. These results insecurity specially to those who don't have the guts like those who let pride and vanity invade them. Peer pressure would start here because in every circle of friends there must be the proud one and inferior one. The inferior one would always want to meet the level of the proud one, and the proud would always make those who are inferior to him feel down.
