           It's the week before school starts. Alice is shopping for clothes with two friends, Nina and Vicki. Alice puts on a black jacket, turns to her friends, and says, “Hey, what do you think?”  

          The girls look at her and both start laughing. “No way,  Alice!”

          Nina laughs. “That's a man's jacket.”

          Alice feels a little angry. “Yeah, well…I like it”:

       “Yeah,” says Vicki, “but what will people at school say?”

          Alice thinks for a moment. Then she takes off the jacket. “Yeah, you're right.”

          We all know about it. Your friends wear certain clothes or listen to certain music. You don't want to be different. So you do those things too.

          Fifteen minutes later. Alice is still thinking about the black jacket. “Yeah, there's peer pressure to follow others.” She explains. “If your clothes or hair are different, people make fun of you. You know, they laugh and point.”

         Vicki agrees. “It's true .You even have a certain kind of boyfriend or girlfriend! I think these 'rules' are childish (幼稚的). But when you're different, you feel like an outsider. And that's hard.”

        Alice walks away.

       “Hey Alice,” calls Nina. “Where are you going?”

       “To get the black jacket. I don't care what others think. I like it, and I'm buying it.”
