Through the Internet, we can make friends from different regions and even different countries. Therefore, we can learn a lot from them and broaden our horizons. Even better, online friendship is more pure. Once you find him or her commenting, you can easily stop contacting him.
However, making friends online also has disadvantages. As we don't know each other, you are easily deceived by them, and it is difficult to establish long-term friendship online.
In a word, we should be careful when making friends online. It is advisable for you to make friends who share your interests.
