I agree with Jennie. I am a bit like you. I hate groups. My parents always sent me to some vacation camp. I hated it and did my best to be obnoxious to be sent home. I like small groups as well. I love dancing, but I avoid going to parties with other people's car because I want to be able to leave anytime (usually pretty early). I am comfortable teaching because in a way it is anonymous.
Is that wrong ? Why should it be ? Why do we have to be all the same ?
Look at the bright side. You are not a follower. You will never jump over a cliff just because everybody else is doing it.
