Like me, I don't really like going out with large numbers of groups of people. Though I can't escape a larger group since my friends and their friends became mine but I don't consider them closed. They just perhaps like my company so when they'd have plans they called me. It's fun sometimes but most of the time it's not and just what you said, it's just too noisy.
Yeah, the companions make the food better because of the fun we spend together.
There's nothing wrong with having a larger friends group, it's just not my style though I guess. I prefer quality over quantity.
