I am a fifteen-year-old girl. I have a problem now. I want you to give me advice. Three months ago, I knew a boy on the Internet. He saw my picture on the Internet and wanted to make friends with me. I found that he had the same character as me. We both like drawing and swimming. We both hope to travel all over the world. We got on well soon. We often talked with each other on the Internet. Two weeks ago we began to talk on the phone. We both felt comfortable when talking to each other, as if we had been good friends for a long time. Last week we hung out (闲荡) together because he doesn't live far from my home. We talked a lot and enjoyed ourselves together in the gym.
However, some of my friends said that I shouldn't make friends on the Internet. They also said that the boy might be dangerous. I don't know what I should do. I don't want a close relationship with him, but I'm really happy with him. Should I talk about this problem with my parents or teachers? I'm afraid that they would be angry and think I'm a bad girl. So I ask you for advice. Please help me.
