Lin Wenqian is a girl student. When she was on a busy bus last month, she felt someone touching her. She was so afraid. Zhou Bin, 12, is a boy. He likes to chat on the Internet. But once a stranger said lots of dirty things to him. Zhou was so surprised! What can students do when this kind of thing happens? Here is some advice from some teachers and students: Don’t be afraid. Ask him or her to stop at once. If he or she doesn’t listen, try to turn to others around you and call for help. Keep calm. Be serious and keep a cool face. Say you don’t like it and show you are angry. If there is no one around, use clever ways. If you only shout or fight to make them angry, it could make things worse! They may take your life. Find excuses ( 借口 ) to run away. Say things like you are waiting for your parents or you want to go to the washroom.
