This exact thing happened to me. I was invited to attend ...but then it was like ...what are you doing here... ( not in a good way) was the attitude.
I never went again and to this day when someone asks me 'what guild to you belong to" ...like I'm not a "real" quilter because I don't belong ... I just tell them my own personal guild it meets every Monday .
The level of discomfort I felt ....was not something I would ever want to repeat. I make it a rule not to go places I'm not wanted, everyone is happier that way.
