Making friends on the Internet

Now, lots of students like surfing the Internet. They also like making friends on the Internet. But every coin has its two sides. Making friends on the Internet is very good for most students. Because they can hear something interesting from their friends. When they are not happy, they can also say their feelings to their friends. But making friends on the Internet is dangerous. Because they don’t know who they are. I think we’d better not make friends on the Internet. Or we should be more careful.
