I had the same experience with a group. I took my 90 year old friend because she no longer drives. Out of 100 people, only two spoke. Sometimes it is just a matter of common courtesy. They know when you are a stranger. My mother taught me to be kind, especially to strangers in a group. I have no desire to join and I have been back three times. I wasn't looking for an invitation to the next family gathering, just wanted to meet talented quilters to learn more. This board is my guild too.
