Some people believe that the Internet has many negative aspects. Talking to people online or having a friendship with someone you only talk to on the Internet isn’t a replacement for real-life communication. While it can connect you with other people who use a smartphone, face-to-face contact with others is important to help you maintain healthy relationships.
