My 19 year old son doesn't go out very often. I get the impression that his friends are out every weekend, pubs, clubs, etc. My son doesn't seem to enjoy this scene or drinking alcohol very much. I'm pleased he doesn't drink a lot but I'm worried that because he doesn't like these things that he's going to end up lonely with no friends. He doesn't seem unhappy, has a good job, a girlfriend, drives & goes to the gym. He's also been on boys holidays the past 2 years. Am I being silly worrying? Can anyone else relate to a similar situation?
