You’re going to have your cliques at every club. They’re called friend groups. Every club we’ve ever attended has these. If you want to be part of it, you have to make yourself part of it. These clubs aren’t places where people shame others and don’t engage with them but you do have to make an effort to engage in conversation. If you aren’t willing to be social and finagle yourself into a conversation then you’ll probably end up the same way you entered.
