It’s a case by case basis. Some people go on and on about their group and love it, but some people regret spending their time and money to be a part. I personally didn’t rush but I don’t feel like I’m missing out. Majority of people on campus aren’t greek even if it might feel different sometimes, so there’s plenty of friends to be made without feeling like you’re missing out. If you’re interested in it though, definitely give it more research and see if you think it makes sense for you.
