Cliques are just groups of people who are uncomfortable stepping beyond their comfort zone. We have all belonged to them ..if we are honest with ourselves. Nothing new. It is human nature. We all tend to gather with our personal friends, etc. My personality is to talk to people in elevators. I am not "shy". And, no, I never expect to "belong" with every group. Seek out others who are sitting alone, introduce yourself and start a conversation with small talk. You will find your niche. And you will make others feel welcome in the meantime. My fav line is..."Step out your box"!
I, too, prefer the quilds that are smaller and loose. I don't have time to sit on a Board, a committee, run a Quilt show, etc.
