I knew of people in college that were socially inept probably because they spent much of their time in isolation working on computer hobbies growing up. I'd see them in the labs and they always seemed really depressed. It seemed like they lamentee not having friends being invited places, etc... I get it because when I moved to a new city I felt like I had that same problem except only temporarily. But living your life with minimal human contact with others? I'd regret that.
