On one hand, it is very rewarding. I can keep in touch with my old friends on a regular basis through various chat apps. We can share our joys and sorrows instantly, which helps to strengthen our bonds. It also enables me to make new friends with similar hobbies. For example, I joined an online reading club and met some great people. However, there are also concerns. Sometimes, the information online can be shallow and false. I once argued with a friend because of a misunderstanding caused by a wrong piece of information on the Internet. Also, spending too much time chatting online may limit the time I spend with my friends in person. But overall, if I concentrate on using it properly, the Internet can be a good basis for maintaining and developing my friendships. 学科网（北京）股份有限公司 $$
