　 A peer is a person who is about the same age as you. Peers affect your life, whether you know it or not, just by spending time with you.

Peers can have a good effect on one another. Maybe another student in your science class taught you an easy way to remember the planets in solar system. Maybe you got others excited about your new favorite book and now everyone’s reading it.

　 However, sometimes peers affect one another in another way. For example, one kid in school might try to get another to cut class with him, your soccer friend might try to persuade you to be mean to another player and never pass her the ball, or a kid in the neighborhood might want you to shoplift with him.

Some kids give in to peer pressure because they want to be liked, to fit in, or because they worry that other kids may make fun of them if they don’t go along with the group. Others may go along because they are curious to try something new that others are doing. The idea that “ everyone’s doing it” may influence some kids to leave their better judgments or their common senses behind.

　 Peer pressure can be extremely strong and hard to get rid of. Experiments have shown how peer pressure can influence someone to change her/ his mind from what she/ he knows for sure is a correct answer to the incorrect answer--just because everyone else gives the incorrect answer! That holds true for people of any age in peer pressure situations.

　 It can be hard to walk away from peer pressure, but it can be done. Paying attention to your own feelings and beliefs about what is right and wrong can help you know the right thing to do. Inner strength and self- confidence can help you stand firm, walk away and resist doing something when you know better.
