1. Every college discussion about community values, social climate and behavior should include recognition of the developmental importance of student autonomy and self-regulation, of the necessary tension between safety and self-discovery.
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.
